Mercedes can’t indemnify you. Local police and prosecutors make those decisions.

Nope. Local police and prosecutors have no authority to make decisions on liability. Their authority is limited to criminal matters. However, police reports can generally be used as evidence in civil trials where judges and juries make decisions about liability.

There may be some circumstances where a driver operating a Mercedes-Benz vehicle using Drive Pilot could be committing a criminal offense. For example, I think sitting in the driver's seat while intoxicated would still be illegal even if you're not actually driving. But that is separate from liability.

Are you thinking of immunity? Indemnity is regularly contracted between private parties. (Also, police can’t give you immunity in America.)
