Just because you prioritize transit in cities, doesn't mean that transport costs in general rise. Transportation between cities can remain car driven as those are inherently sparse areas anyway; you don't need to reduce use of all types of cars in cities, industrial use / deliveries can still exist in those systems anyway; and as a long term idea, self driving deliveries may also drive some of these costs later on. Additionally, while cost of transport rises for car commuters, it very well may fall for transit ones and especially for those car commuters who switch to transit. So it's not a given that prices would uniformly rise.
