Gary, right, and isn't "Following too Closely" a ticketable offense at least in PA? How do you classify the runaway shopping cart and who is liable? The person who left it(now long gone), the store to whom the cart belongs for lack of timely pickup. This may be one for SCOTUS. But then again maybe not.In my opinion, if I hit someone who 'suddenly stops', I'm at fault for following too closely, AND careless driving. Try that one on the 'cop and hitter' for size!
PS: Oh Yes - also, in my opinion, there is no such thing as an 'accident' involving damage to my car unless a tree falls on it or a meteorite hits it while I'm on the road driving. Any other contact between cars is driver error - mine or the other driver (even in case of a mechanical problem on the car, as that represents a lack of maintenance on my or the other driver's part).
