I think we will see EV incentives start to be rolled back now that there are quality EV products (Tesla, Brammo, Zero) that are selling well.
Teslas are backed up months, Hollywood Electrics are selling the 2013s faster than they can get them in, and Brammo sales seem to be doing solid as we see photos of bikes being delivered in Europe and new Brammo dealers announced on a regular basis. It was really easy to offer incentives when there wasn't anything on the market and it didn't really cost anything. It just looked good.
