There are a number of problems with increasing car utilization. They tend to prevent other forms of transport from co-existing as busy roads are not attractive to walk/cycle/scooter along. There's also the sizable amount of pollution from tire and break wear which is not solved by EVs (except electric scooters/bikes - they produce a negligible amount of tire particulates due to their reduced weight).

When you have increased car usage, there's also a demand for car parking and once you start assigning a large amount of space for car parking, you end up pushing facilities further apart. This means that more journeys then become impractical except via cars and the problems increase.
