It may not detect all obstacles, Tesla cautioned when it released the update. Be especially careful around quick moving people, bicycles and cars.The cars in Smart Summon mode often drive down the middle of parking lot aisles, rather than hug the right side like a typical driver. The Teslas also take corners slowly, or sometimes too fast — not halting for stop signs. Speeds bumps can confuse the technology.Tesla owners use a map in the app to tell the car where to go. But sometimes the aerial imagery is out of date, making it harder to understand where you're telling the car to go. Even when the map is accurate, the cars don't necessarily stop at the perfect spot.Smart Summon is a classic Wild West technology, and regulators might crack down on it. The National Highway Traffic Safety Administration felt moved to weigh in, saying it's studying the feature and won't hesitate to act if a safety defect is found. Tesla has a habit of giving customers imperfect new features that can be misused. Its Autopilot software, which steers, accelerates and slows down the car in some settings, has been criticized by the National Transportation Safety Board for not being restricted to suitable roads.Big box retailers, whose parking lots are popular with Smart Summon users, haven't taken action yet. Many of the nation's largest retailers all declined to comment, including Walmart, Target, Kroger, Home Depot, Lowe's, Whole Foods, Walgreens, CVS, Macy's, Aldi, McDonald's and Bed Bath & Beyond.
How insurers handle Smart Summon is also unclear. The technology is so new that insurance issues are still being worked out, according to a spokesman for the Insurance Information Institute.
Major insurance companies such as State Farm, Geico, Providence, Liberty Mutual and Nationwide declined to comment. An AllState spokesman said claims would be handled on a case-by-case basis.
So for now, don't be surprised to see an empty Tesla roaming a parking lot near you, maybe even with a humorous prop behind the wheel.As one Tesla owner described his experiences — Everybody loves it, whether the skeleton's in it or not.
