As some of you may or may not be aware cars are now being built with crash data recorders.

So when a car driving by its self, (active cruise control) and above in technology.
Has a crash and the driver says he wasn't in control or the car braked, didn't brake etc. when it shouldn't, the insurance companies are going to look for someone to blame.

If you just so happen to be the last garage that looked at it and didn't follow the manufactures procedures correctly you could be blamed.

Guess that your choice how you decide to go.
