Cars Kill Cities
The post is right, and even more so for developing world cities that emerged before cars were around.However the post is also naive.  Cars are usually much faster, provide much better shelter from the weather, and are much less tiring than trying to lug bags from one place to another on buses or other public transport.  They also place far fewer constraints on when you can travel.Of course it's possible to structure one's life so as to deal with all of the issues.  I have lived half of my adult life without a car, including 4 years in the SF Bay Area, and I managed.But let's stop pretending that there isn't a trade off.  Cars are very very convenient.  The key to reducing the need for cars is not just good public transport - it's services that reduce the reliance on traveling to get chores done.  Things like grocery deliveries, laundry pickup, and amazon.com.It would be a lot easier to rely solely on public transport if you never had to carry anything.
