Well, I'm in the midwest US, so winter can be a bit harsh for walking or biking (though not this year thus far). Most of the time I drive, I'm dragging kids somewhere. It's inconvenient to walk with them.

I have been walking and or biking when it's just me, and I don't need to haul much. I've lost a lot of weight recently, so I can actually bike to work in the summer and not be a sweaty mess when I arrive, so that's a nice change.

We are taking about moving outside the city to have more space, which means not driving will become less possible for almost everything. Today I have groceries, dentist, and doctor within half a mile, and I've walked or biked to those places many times.

Bottom line, most of the time I'm either dragging kids around or I'm in a rush. Driving is very convenient, and is hard to change.
