As I've written about this on the Tesla sponsored board, this bill is a joke. It adds significant complexities, such as how are they going to do the "rolling expiration" stickers starting in 2019, additional recordkeeping and background checking (did the car have a sticker issued previously?). Dumb dumb dumb.
The yellow stickers that were issued in 2005 were set to expire in 2007, extended to 2009, extended to 2011. Why not do the obvious and simply make the stickers valid to some future date, and based on HOV crowding, extend that or not.
Remember, all the green sticker hybrids are out of the HOV lane as of 1/1/2019. Unless the auto manufacturers bribe (I mean lobby) a state legislator. This will remove a substantial amount of HOV crowding. And with better enforcement, removing the large number of HOV lane cheaters could further open up those lanes.
I encourage any California owner with white stickers issued before 1/1/17 to contact your state assemblyperson and state senator, explain how the (still a bill, but very likely to be signed by Gov Brown) law discriminates against the very people who took a chance on non-ICE vehicles in their early days.
