I’m also of the drive it into the ground school of thought. In fact, of all the cars that we replaced, they were still drivable for in-town, but not safe or reliable enough for long-distance travel on the higway. One was sold for scrap when the bottom started rusting out, but all the rest were just because they could not be safely taken on the highway.
The more-and-farther thing may be true for the city, but it’s still not really true for the highway. You’re running nearly purely on the gas engine when traveling at constant highway speed.
As for the plug-in hybrids (or electric cars), I don’t have a problem with them if they can get the recharge fast enough. I can only go about 300 miles at a time in my little Subaru, which I think is the number I’ve heard for the range of a really good electric. That’s fine, as I don’t want to drive more than about 4 hours at a time without taking at least a few minutes to get up, stretch, hit the restroom, maybe get a bite to eat, and so on. But I can gas up and go in less than five minutes if I want to. If I have to stop for an hour every four hours to let the battery recharge, I will not be happy. They’d have to be able to recharge in no more than 15 minutes. Oh, and I wouldn’t pay more than I am now in gas. As for the question about payments, if you figure that you spend at least $100 a month just to get the car running, does it really matter where it hits you? Sure, the grid and powerplants would need an upgrade, but we would have the benefical effects of being able to get pollution centralized and possibly even go nuclear.
