Over the next five years or so, I expect some places will start charging EVs a toll based on the miles driven to compensate for the 'lost' revenue they collect on the sale of gasoline. Most EVs are heavier than similar ICE vehicles, and that puts a bigger wear factor on the roads and bridges. You might rationalize not doing that since they don't pollute as much, but their heavier weight does put more rubber dust into the environment that most don't consider when they review pollution...so, it's sort of a toss-up. IMHO, they should check the REx engine for pollution levels, and there's a routine built-in to force it to run so it can be checked. But, many states these days are not actually doing a smog check and are relying on finding no faults stored in the vehicle from the OBD-II port. My state used to do a tailpipe check, but now rely on the computer's report in the car that everything is working properly and things have been serviced on time.
