What I really think should happen is that when anyone hits a pedestrian or cyclist, they should just have their car immediately impounded indefinitely, and that should just be the end of it. I'm not 100% sure, but after that guy hit the cyclists in Florida, didn't they allow him to drive away? If my memory is correct, that is INSANE!
Not renewing the stickers is a good idea- now we just need to get the cops to pay attention and get the tow trucks ready!
