In a crash, I'd rather be in
In a crash, I'd rather be in a car that warns you and shuts itself down than a Volt or a Leaf. Even the driver in Mexico that plowed his Model S through a wall and smashed into a tree walked away from the crash.
The Tesla is designed to protect the driver, not itself. The fires caused by hitting road debris didn't spread into the passenger compartment, and both times, the drivers ignored the car's emergency warning. It is still the safest car on the road.
