Norms are eroded when they are violated and there are no consequences.
'Why should I pay attention to carpool lane signs if there is not penalty for violating them? I won't.' Lots of people think this way and now they are just another lane.
Violations of norms are also contagious. If one traffic law doesn't matter, maybe we can get away with violating it more. 'I did it before and didn't get caught. Maybe I can keep doing it to save time'
It prob takes at least 6 months for the money to be available, a bunch of time to figure out land permissions and contracts, time to negotiate with suppliers. 2 years means first stations prob starting to roll out about now.
