Chandigarh does Singapore: Puts a cap on number of vehicles that can be sold; Road tax = 50% of car price.
Doesn't matter whether you have an infra like Singapore or not, but you can always have policies like them.
Starting Jan 2018, those who will purchase a car worth Rs 10 lakh and above, will have to shell out half the price of the car as road tax, which at present is 6% the cost of the vehicle.
Those interested in purchasing a car will have to buy a certificate of entitlement (COE) from the administration after paying a prescribed fee. The certificate will grant the person legal right to own, register and use vehicles within the city for a period of 10 years Plus, when you are buying the car you 'd be needed to submit a certificate of availability of parking space.
A step in the right direction? How is the public transportation in Chandigarh (compared to Singapore)?
Note that this is a draft policy and is awaiting feedback/approval from the stakeholders.
