2. I’ve seen a full range of disabilities on transit as well. Plus, isn’t it better for the disabled if it’s easy for them to drive since the roads and parking are mostly free of able-bodied people?
3. If you’re in the countryside, you can still drive when you need to. You can park at the edge of a city and take quick efficient transit to whichever internal part of the city you’d like. Also, living somewhere inconvenient like the countryside is a choice, and that inconvenience should be considered when looking for a place to live
4. I travel for work and have never needed a car. If you do, see the answer above for those in the countryside, that applies too
We can all make cities better without being 100% binary. Cars can be the exception rather than the rule, though
