I have to agree somewhat with bewildering, The only place where I found public transplantation cheaper than driving was in Asia, But that was likely because it was very heavily subsidized.
I hate being limited to what you can carry on the train, and waiting 30 minutes or more for the next train, then you end up walking half a mile to your destination.
PITA IMO
I like personal vehicles.
Plus if it is very cold or hot or raining just adds to the misery of PT.
Self driving cars would help however, I still would want to own my own.
