On a recent road trip I noticed traffic was terrible on interstate 95, especially through South Carolina. Maybe it was because it was the Thanksgiving weekend, but maybe there are other factors involved?
If the big-three went out of business, then eventually only people who could fix their cars would be driving because when the cars break down the people who simply buy new ones wouldn't have anything to buy. So over time, traffic would get better, except for the Japanese and German cars on the road, oh, and the extra pedestrians, motorcyclists, and bicyclists.
