It because the emissions police ( IE the government mafia) want money to give you permission to drive your vehicle. They probably will have some law requiring inspection of all electric vehicle too passed. Lately I surprised they don't charge an extra tax for using rump ribbon. I know they just up and doubled my property taxes by doubling my property appraised value.
It like my new health insurance calling and asking a bunch of stupid; just looking for reason to deny me coverage. Next time they call I going to answer "Brice's Mental Hospital, how may I direct your call?".
