When Tesla announced last month that it would push out a software upgrade to allow Model S owners to park their electric car in a garage or perpendicular spaces without anyone behind the wheel, it was seen as yet another step toward a fully autonomous vehicle. That was until researchers found the new “Summon” mode contained a small safety issue. Our intrepid colleagues over at Consumer Reports, who were quick to test Summon after it was announced in mid-January, found that while the feature was easy to use, it lacked some safeguards to protect drivers, passengers, and pedestrians. Summon, which allows owners to park from outside the car as long as the sedan is within 33 feet of a garage or narrow space, is operated when a user is within 10 feet of the car and engages a key fob or the Tesla app. While the operation is fairly straightforward, CR found that the feature lacked controls to stop the car from moving forward after it was engaged. Under the current system, when summoning the vehicle with the key fob or the app, you don’t have to constantly hold down the Summon button.
