Where I live, half the year it's painfully cold outside. Then in the summer we alternate between unbearable heat (because we're not used to it) and torrents of rain recently.
We also don't have a subway system in any of our cities, have lower density cities because we don't have a huge population in general, and have better driver education than much of the US.
I realize it would be optimal for society for me to take public transit, but in these conditions I'd rather drive. And if I need to go somewhere close, walking is quicker than public transit (and in the winter, generates SOME heat. Standing around at a bus stop, not so much).
I promise if I ever move to NYC, I'll take the Subway when something is out of walking distance. I did when I visited. It was fine.
