It seems nuts to me, that in a shared medium such as public roads, that there isn't some upper bound in collision liability for unintentional damage caused to other vehicles. Given the average cost of a car today, this incident would likely clear whatever bar is set anyway, but given the necessity of driving (at least in the US), the idea of someone making peanuts be liable for multi-tens-of-thousands repair bills for low-speed collisions because someone chooses to drive a car that costs as much as a house, just feels like an unnecessary kick in the nuts.
