Agree.

When I was getting my pilot's license, I learned to be hyper-aware of another airplane that was less than say 1000 feet from me. But the strangest part of those lessons was getting back into my car afterward and getting onto the 417, where I was a couple of feet away from other cars, also going 75mph. I was completely at these other drivers' mercy: I had effectively no time to react to them, and knew from experience that lots of drivers are just plain awful (and this was really before you'd see people driving while texting with one hand and changing their kids' DVD in the other.)

It was very, very scary. Total loss of control — far more than in an airplane, where to a much greater degree if things go sideways, it was probably your fault anyway.

The other interesting thing about the scary drive was how long it stayed scary: maybe ten minutes, tops. After that — business as usual. Didn't even think about it.

It's interesting what we can get used to.
