For me, context matters a great deal. In the city I grew up in, half an hour isn't all that far, because I regularly had to drive for that length of time to get to the places I went to most often. In the city I live in now, half an hour is incredibly far, because it takes me entirely outside the city limits (no matter where I start from). Half an hour in a large city feels relatively nearby, but half an hour in a small city can often take you from one end to the other (or more).
On the other hand, where I live now, I regularly drive to other cities for day trips, and have to drive at least an hour and a half one way (but I'll drive up to two hours away). Where I used to live, the closest city was two and a half hours one way, so I never drove there unless I was spending at least one night (although I had family there, so I rarely had to pay for accommodations).
I do like driving, so I'm willing to go relatively far afield if it seems worth it to me. I usually won't go somewhere (without a really compelling reason) unless I am going to spend at least as much time at the destination as I will driving to and from. Otherwise, I can usually find other ways to get what I want, wait until I have a more compelling reason to go, or find other things to do closer to home. I'm more likely to spend more time driving than being in a location if the drive itself is new to me, because then it becomes part of the entertainment. I don't enjoy driving on routes I'm familiar with quite as much, although I often don't especially mind it, either.
