The fastest I ever drove was 120 on a German Autobahn, and then for only a few milles, between Nuremburg and Munich. Needless to say, it feels nothing like driving at 80 or 90. Weird. I have been content since to look out of windows as the airplane takes off.
Yeah, you really have to wonder how Nascar, rally, and f1 drivers drive as fast as they do.
