If pollution is the issue then ban pretrol-powered cars and give citizens 5 years to move over if they want to continue driving. Offer subsidies for low cost models so its affordable for a modest percentage of the population.
Not only would this cut down on pollution. It would decrease traffic, and still allow those who want a ride from a (taxi, uber, etc) to continue doing so.
