Of this I have no doubt.
Urban sprawl, overbuilding, congestion, longer commutes, and inadequate roads have a hell of a lot more to do with tailgating than just about anything else, including NASCAR.
Yep. We've let ourselves build the very infrastructure of our society around the automobile, so this is what we get. I would add to that list the general self-centeredness of people these days. Everybody is stuck in their own little world and do not think of others first.
Case in point: Just this morning I had to go to Home Depot to get a new water filter for my refridgerator. The weather in Lansing this morning is a mixture of rain, sleet, and snow. Not only did I had people tailgating me the entire way there because I was actually driving the speed limit due to the bad conditions, but upon arriving at Home Depot I got out of my car and started walking to the entrance at the same time that a man in a HUGE Ford truck started driving towards the exit. Instead of slowing down and letting me walk safely across the drive into the store, since afterall I'm walking in the freezing sleet that's pummeling everything outside, he speeds up and then gets mad at me because I'm in the process of crossing the drive.
Pedestrians. What a pain in that ass, eh? Especially when I'm in my comfortable truck, sheltered from the weather and they make me lose 1/10th of a second. Thanks, buddy!
