Tesla’s automated parking feature will be rolled out to U.S. owners next week
Tesla is preparing to roll out a more capable and robust version of its automated parking feature known as Enhanced Summon next week, CEO Elon Musk tweeted Saturday.
The tweet comes just days after the company released a new version of Navigate on Autopilot, an advanced driving feature that is viewed as a step towards full automated driving on highways.
In the tweet, Musk writes “Tesla Enhanced Summon coming out in U.S. next week for anyone with Enhanced Autopilot or Full Self-Driving option.”
Enhanced Summon is a parking assist feature designed to vehicles to navigate a parking lot autonomously and find its driver — under specific conditions. For instance, the driver, who uses the Tesla app to remotely call the car, must be within a certain distance of the vehicle.
Using the feature, the vehicle will pull out of a parking space, navigate around objects and come to the owner. Musk has been teasing this feature for some time now and owners in the early access program have used it. It’s started to be available more widely a few weeks ago to some owners. (There are already numerous video demonstrations of Enhance Summon in action) Now it appears it will have a wider release, based on Musk’s tweet.
Tesla’s vehicles are not self-driving. Autopilot is an advanced driver assistance system that can be described as a Level 2 system, a designation by the SAE that means partial automation. Level 2 can control two ADAS features simultaneously like adaptive cruise (accelerating and deceleration along with the vehicle ahead) and lane steering in certain conditions. However, the human driver is expected to maintain control at all times.
(Others have referred to it as semi-autonomous system, but that terminology has been recently shunned by industry insiders)
Navigate on Autopilot, which is supposed to guide a car from a highway on-ramp to off-ramp, including navigating interchanges and making lane changes, is Tesla’s most advanced driver assistance feature to date. The feature was initially held back when the automaker released the latest version of its in-car software, 9.0. When Navigate on Autopilot was eventually released in late October, Tesla placed some limitations on it, including that it mad a lane change suggestion that required the driver to confirm by tapping the turn signal before it would proceed.
In this newest iteration, drivers will now have the option to use Navigate on Autopilot without having to confirm lane changes via the turn stalk. The new version offers “a more seamless active guidance experience,” the company wrote in a blog post April 3.
For a bit of history, Tesla announced in October 2016 that it would started producing electric vehicles with a more robust suite of sensors, radar, and cameras—called Hardware 2—that would allow higher levels of automated driving. Owners of these Hardware 2 vehicles would be able to opt for one of two advanced driving packages, Enhanced Autopilot or Full Self-Driving, the latter of which is supposed to push the automated driving feature to new levels of capability and eventually drive autonomously without human intervention.
Owners with Enhanced Autopilot have vehicles capable of adaptive cruise control, Autosteer (essentially lane keeping), Summon and Navigate on Autopilot. But then in October 2018, the same month it started rolling out Navigate on Autopilot, Tesla removed that “full self-driving” option (FSD).
Then suddenly this year, Tesla changed the terminology and pricing again — and it brought back FSD.
Enhanced Autopilot is no longer available to new owners. Instead, owners can opt for Autopilot or FSD. Autopilot includes the Autosteer and adaptive cruise control features.
Owners who want the more advanced features like Navigate on Autopilot have to buy FSD. Navigate on Autopilot is considered a step towards that still on-met full self-driving promise.
Autopilot costs $3,000 and Full Self-Driving, costs an additional $5,000. So to get FSD owners have to plunk down $8,000.

GPS Rollover is today. Here’s why devices might get wacky
The Global Positioning System time epoch is ending and another one is beginning, an event that could affect your devices or any equipment or legacy system that relies on GPS for time and location.
Most clocks obtain their time from Coordinated Universal Time (UTC). But the atomic clocks on satellites are set to GPS time. The timing signals you can get from GPS satellites are very accurate and globally available. And so they’re often used by systems as the primary source of time and frequency accuracy.
When Global Positioning System was first implemented, time and date function was defined by a 10-bit number. So unlike the Gregorian calendar, which uses year, month and date format, the GPS date is a “week number,” or WN. The WN is transmitted as a 10-bit field in navigation messages and rolls over or resets to zero every 1,204 weeks.
Since that time, the count has been incremented by one each week, and broadcast as part of the GPS message.
The GPS week started January 6, 1980 and it became zero for the first time midnight August 21, 1999. At midnight April 6, the GPS WN is scheduled to reset, which could be problematic for legacy systems and impact time and the time tags in location data. Utilities and cellular networks also use GPs receivers for timing and controlling certain functions. For instance, the U.S. power grid uses timestamps embedded in GPS. The U.S. Department of Energy says that “GPS supports a wide variety of critical grid functions that allow separate components on the electric system to work in unison.”
It should be noted that the WN restart date could be different in some devices, depending on when the firmware was created.
The bug, which some has described as the Y2K of GPS, will cause problems in some GPS receivers such as resetting the time and corrupting location data. The GPS WN rollover event may hurt the reliability of the reported UTC, according to U.S. Department of Homeland Security. HDS said an GPS device that conforms to the latest IS-GPS-200 and provides UTC should not be adversely affected. The agency also provided a word of caution:
However, tests of some GPS devices revealed that not all manufacturer implementations correctly handle the April 6, 2019 WN rollover. Additionally, some manufacturer implementations interpret the WN parameter relative to a date other than January 5, 1980. These devices should not be affected by the WN rollover on April 6, 2019 but may experience a similar rollover event at a future date.
If you own a newer commercial device with updated software, it’s most likely fine. But double check and make sure the software is up-to-date.
The U.S. Naval Observatory suggests contact the manufacturer of your GPS receiver if you have been effected by the GPS week number rollover. Some GPS receiver manufacturers can be found at the GPS World website.
Work has been done to avoid this kind of rollover issue — or at least punt it down the line. The modernized GPS navigation message uses a 13-bit field that repeats every 8,192 weeks.

Scooters may kill the sharing economy?
TechCrunch’s scooter aficionado Megan Rose Dickey dived into the current state of the scooter market, and came back decidedly non-plussed. Scooters seem like a viable solution to the last-mile problem of urban transportation, but the reality is that the sharing economics behind them are weak, and huge regulatory barriers are being erected that will almost certainly slow their advance. Even worse, sharing may disappear entirely:

Space tech rockets higher
Venture investment in space technology is hitting stratospheric heights in recent quarters. But investors in the sector are betting it will rocket higher still.
The latest example of high-velocity funding is satellite internet startup OneWeb, which recently announced a galactic-sized $1.25 billion venture funding round in the wake of a successful launch. The financing, which included a long investor list featuring the ever spendy SoftBank, brought total funding for the Arlington, Va. company to a whopping $3.4 billion.
But OneWeb is far from the only space tech company to secure a big round recently. A Crunchbase News roundup of large investments in the sector unearthed a sizable list of companies attracting attention and big checks from venture capitalists, with at least a half dozen securing rounds of $50 million or more since 2018.
What’s the draw? Largely, it’s the oft-repeated tale of a startup sector seeing valuations rise as early-stage companies mature, said Chad Anderson, CEO of investor group Space Angels.
“The barriers to entry came down in 2009, when SpaceX provided increased access to space through low-cost launch and transparent pricing,” Anderson said. “We saw the first pioneering companies, like Planet [former Planet Labs]*, take advantage of that new access starting in 2013.”
Now, the crop of space tech companies that launched five or six years ago is middle-aged by startup standards and ripe for larger, later-stage rounds.
Economics of satellite design and launch have also become a lot more compelling for investors in recent years. Whereas satellites previously cost hundreds of millions (or even billions) to design, manufacture, and launch, today a small satellite can be built for tens of thousands of dollars and launched for a few hundred thousand dollars, Anderson said.
Venture capitalists seem to like that math. Over the past 10 calendar years, Space Angels estimates that venture capital funds have invested nearly $4.2 billion into space companies. Of that total, 70 percent was deployed in the last three calendar years.
More firms are getting into the space, as well. Currently, Anderson calculates that just over 40 percent of the Top 100 venture capital firms now have at least one space investment. Their investments are concentrated in two areas: satellites and launch technology, particularly for the small satellite space.
To get an idea of where the money is going, we put together a chart below showing the space tech companies that have secured some of the largest funding rounds since last year:
While space tech is generating a lot of venture investment, however, not a lot of startups have yet made it to exit. That’s not entirely surprising, if we presume that typical venture startup-to-exit timelines apply. If the current crop of funded startups launched in the 2013 time frame, we’d expect to see exits pick up in a few years.
It is worth noting, however, that the one most famous and pioneering of the current crop of venture-backed space companies, Elon Musk’s SpaceX, has also stayed private. Certainly SpaceX has the name recognition and track record to support a blockbuster IPO.
Yet Anderson contends that’s unlikely to happen — at least not for a very long time. For one, Musk has laid out the company’s ultimate goal as colonizing Mars. That doesn’t jibe well with the typical public company duties, like meeting quarterly numbers. It doesn’t help that Musk has already gotten into hot water with regulators for his approach at Tesla.
Yet as SpaceX pursues its grand ambitions, the company has also served as a launchpad for a number of other space tech entrepreneurs — we put together a list of nine startups with a SpaceX alum as founder or core team member.
So while colonizing Mars remains a risky bet, the odds in favor of blockbuster space tech exits on Earth are getting a lot higher.
*Planet and SpaceX are Space Angels portfolio companies.
