The problem with cars is that people want contradictory things. They want a car, preferably their own car rather than a shared vehicle, so they can travel when and where they want, without being tied to timetables and bus/train routes. They also want to be able to park at or near their own property. However, they also want fewer cars on the road, less pollution, and less crowded roads.
The obsession with car ownership led to the insane schemes of the 60s and 70s where perfectly sound housing (which in many cases had survived the Blitz) was torn down to make way for flyovers, ring roads, urban expressways and the like. Then, in the 80s and 90s, out-of-town shopping malls became 'the thing', increasing people's dependency on the car, especially as public transport was privatised and less-profitable routes were axed. Because public transport had become mostly for those too poor or too young or too old to drive, there was little effective resistance to this.
But, of course, everyone, though perhaps recognising the problems arising from mass car ownership, is resistant to changing their own pattern of behaviour because they enjoy the freedom of choice of when and where to travel that owning one's own car enables.
