#SmartSummon

For some strange reason, U.S. road safety regulators are showing an interest in a Tesla feature that allows driverless vehicles to navigate tight, crowded public spaces on their own — one Tesla admits “may not detect all obstacles.”

Clearly, by investigating reports of Tesla’s Smart Summon feature going awry, the National Highway Traffic Safety Administration is standing in the way of progress, or so some brand diehards would have you believe. To others, the agency’s scrutiny is overdue.

As you read here yesterday, Tesla’s biggest over-the-air software update to date has brought Model S, X, and 3 owners a host of new features, with an especially ominous (or exciting, depending on your level of trust) feature reserved for the true believers.

That Software Version 10.0 feature is Smart Summon — a way of getting your vehicle to drive to you upon exiting a building. Open the mobile app on your phone, press the necessary buttons, and your Tesla will pilot itself like the Mary Celeste to your arranged rendezvous point. Presumably, you’ll have your hands full of children and shopping, though Tesla says you’ll have to keep tabs on your vehicle — keeping it in in your field of vision — lest you find yourself liable for a fender-bender or worse.

It kind of defeats the purpose of the feature. If your attention is distracted by whiny kids or something else, how is it more convenient (or even possible) to stand there and watch your car make its way towards you, alert and ready to release that button and stop the Tesla in the event of a wayward shopper, vehicle, or rogue action on the part of your own car? How hard is it to walk over and get into your own car and drive off, especially considering the feature’s beta nature and Tesla’s long list of Autopilot fails?

Naturally, owners began testing Smart Summon the second it arrived.
