Not to worry. I'm sure there will be a new autonomous vehicle registration fee to implemented to help offset any losses. This registration will of course be on top of any existing registration fees.

They could also use some sort of algorithm that looks at each driver's record. If you have a history of speeding, they can just go ahead and asses extra fees for you since the algorithm extrapolated you would have had more tickets anyways. If you have a clean record, then the algo will go ahead and decide you're "due" for a ticket, and charge you accordingly. Why not, insurance companies do it.
