what do you prefer : a bike or a car?

I don't know where you live, but I live in Michigan. It's 6 degrees outside and theres NO WIND CHILL added onto that temperature. The high for tommorow is 12 degrees, not to mention the little snow storm in the evening. If I even attempted riding my bike any month after December I would certainly be on a fools errand.

For free time if the weather is sunny I prefer the bike.
