However, I agree with Florida on this; the onus should be not be on the accused to prove innocence after a citation is issued. Feels like a 'call us to unsubscribe' time-wasting dark pattern.
That said, if merely being the owner of a tool is sufficient to be guilty of whatever infraction someone else performs with said tool, that has 2 problems beyond the whole "proving your innocence" debate:
1. Why stop climbing up the chain at the current owner when you could keep climbing and say it's all the fault of the manufacturer? I jest, but this illustrates why, despite my first paragraph, it's indeed only sensible that the driver be at fault, so the government must prove who was driving.
2. Why treat cars differently from, say, weapons?
