You wouldn't be alone, I doubt automakers would sell a single solitary L4-capable vehicle without locking it down legally first. My guess is that they'll have to assume liability but with exceptions for if the user modifies the device in any way or otherwise breaks the user agreement. If accidents happen they'd have to have some procedure where they treat it like a plane crash and pore over every detail and issue recommendations/updates to some regulatory body. The downside to this is that these vehicles would likely make even the most cautious myopic octogenarian look like speed racer.
