I would say they could be, but its needs to under strict circumstances. Easiest is with guns, I loan you my gun knowing your going to go and use it to commit a crime, but that is covered under being an accessory. With cars, the only situation I can think of is if you loaned your car to someone you knew was drunk and was going to drive. Or you loaned me the car knowing I was going to use it as a get away vehicle in a bank robbery. But I assume the second case would also be covered under being an accessory to the crime.

But for the purposes of traffic tickets, yea, its ridiculous. It also has a lot of faults. I got a traffic ticket from a red light camera for a car I owned when I was stationed in California. The ticket came to me in Oregon 5 years AFTER I traded that vehicle in (I traded it in right before moving to Oregon) and the traffic cam ticket was from Texas, a state I've never driven a vehicle in. My only presence in Texas has been being in the airport in Dallas. The ticket was also for a year prior to when I received it. So I hadn't owned it in 4 years when it ran a red light in Texas.
