For those of you who grew up in climates with regular snow in the winter, how would you best characterize your approach to cleaning ice and snow off of your car?

I do my best to clean the entire car off every time. It's common courtesy and basic road safety.

I do my best to clean the entire car off when I've got the time/energy. It's a courteous thing to do but not a serious a safety issue, and often a bigger pain than it's worth.

I make sure my windows are clear but I'm not too worried about the rest.

I wipe off a hole just big enough to see through; that's good enough.

Heat on, wipers on, let's go!

I don't drive, how dare you?
