There are mixed results on safety tests for vehicles with auto-pilot features.
The Insurance Institute For Highway Safety focused on adaptive cruise control, lane-keeping, and automatic braking.
The IIHS tested both the Tesla Model S and Model 3, plus a BMW 5 Series, a Mercedes-Benz E-class, and a Volvo S-90.
The Tesla Model S had problems staying in its lane, and both Teslas ended up hitting stationary objects in front of them.
