My commute is now a 15 minute jaunt on the highway to work, this is not by design, nor is it because I moved closer. (In fact 8 years ago I moved farther away from my current place of employment) back then I had a 30 minute commute, and I suppose if I was still living in that one bedroom apartment (with two kids would be hell) I'd have a 10 minute commute as opposed to the 15...
I drive mostly to and from work, other times, not so much.
Gas prices actually around here gas prices have gone up slightly in the past 10 years, but really, when a look on the historical gas price list. in 2004 gas was roughly 70c/l it was 2005 when gas first peaked 100c/l, this morning it was a comfortable 99.7c/l on my drive in to work. So gas prices are slightly higher, but not as bad as they were 5 years ago, and my salary in the same time has more than doubled. It's settled down. hasn't hit 130 in a long time.
Shopping has become less of a hassle as well. It used to be that when I wanted to buy a new motherboard, it took driving around to about 3-4 different stores to get pricing because not every store had an up to date website. that's greatly improved in the past 10 years, same with shopping for furniture, TVs, etc. What used to be a 10 stop shopping trip is usually down to 1-2 now.
10 years ago I was also single, online dating wasn't really all that big yet, so if I wanted to meet someone I had to go out and cruise around. heck back when I was a teenager that was the primary way to meet girls. Now a lot of people meet people online. heck I met my wife of 8 years online. Also I no longer have to drive as much to go on dates with my wife, as we live together. so that's another.
Also entertainment. it used to be more entertaining to go to the mall, the theatre, whatever the kids of the area did to hang out and usually ended up driving there. now, it's more why drive to hang out, we can hangout online and chat online. so no need for physical contact anymore. (which is another study's results that there isn't enough person-person contact with teenagers anymore.
frankly. There has been a lot of societal changes in the last 10 years, and a lot of that results in less driving. plus the whole recession that hit in 2008, kinda put a damper on being able to afford a car in your teenage years.
