to me, it looks like an inevitable process, with the shift from taxation on car ownership to car usage.
will that make cars cheaper? i mean, in places like hk, you can buy a car, leave it to rot at the garage and pay nothing (if you don't pay for carpark). if you don't use you pay nothing at all. that's why it's cheap.
think this topic has been discussed extensively in the erp price hike thread in speaker's corner.
