This may seem like an 'obvious answer' question, but I'm curious about the experience/opinion of members here. Over the years, car have become more reliable, and require far less maintenance than they used to. I'm wondering how much this factor, apart from others, has affected how much people drive. If cars have to have more adjusting/wrenching done on them, then that's obviuosly time they can't be driving. Cars today can pretty well be driven 100k miles w/o much more than a few 15-minute oil changes, 1-2 tire replacements, and maybe a brake job. There are some people who have always driven a lot, whether for work or otherwise, so they just had to spend more time wrenching on their cars. But I wonder how many people 'limited' their driving b/c wrenching on the cars consumed time and money, and as they have had to do less wrenching, they have driven more? Thoughts?
