One way to plan for the next 100 years when building roads but not cause people to buy cars is to have a 10-lane wide verge on one side of the road. Have a row of 30-storey buildings on one side of a 5 lanes each way road, but on the other side the buildings are all set back at least a 10-lane width which is used for car parking, 1-storey buildings, public spaces, etc. If there's ever a need to widen the road, it can be done without demolishing any tall buildings. I see this in new road layouts in China all the time. Of course, under the road will be a new subway system -- another disincentive for people to buy cars.
