Indeed, the creature comforts of a car is probably the big reason they are so successful compared to the alternatives. I rode public transportation well into my late twenties I think. When some folks would accompany me for the trip at times they didn't even own hardy thick winter coats to be able to bear the cold elements outside. People who haven't had to spend significant times standing and waiting to be picked up outside can be pretty shocked at how unpleasant the experience can be, especially given harsher locations.
