I suspect this is not true everywhere. One would need a specific law (as oregon, mass, and others have) that prohibits it. Otherwise it's a vehicle hitting a parked car, which is prohibited. That the driver did not have time to react is not an excuse -- if I small child runs out in front of a car from between a pair of parked cars, it's the driver's fault for the crash.

I think there should be laws like oregon has, but I don't think this is an example of car-favoritism.

Note: I am not a lawyer.
