I once did a tad over that speed (200 kph - 133 mph) in a rented 700 series BMW on the Autobahn in Germany. I wanted to see how fast the car would go with my foot to the firewall. German cars are engineered to handle that type of speed, but after a few seconds, realizing that even a small mistake would send the car, me, and my passengers airborne, I slowed down to a more manageable 140 kph (93 mph). Very much deepened my respect for the skills of professional race car drivers.
Exactly. Those cars are thoroughbreds and everything is just smooth as silk at those speeds. They really are built for those kinds of speeds, but then, like you said, reality filters in your conscience and you realize one small error, bump, debris, other another idiot, and it could be permanent lights out, so you throttle back.
