The "well they drive fast in Germany every day" argument doesn't hold water either.

1) Even on the parts of the autobahn with unrestricted speeds, 130km is still the recommended upper limit, and you're more liable in a collision if you go faster than that.

2) Many people in Germany don't agree with unrestricted speeds, and politicians have compared it to gun law debates in the US.

3) Germany has higher than average deaths per 1000 km driven (for an EU country).
