This can happen at 75 mph or at 50 mph. What's so magic about 120
mph? If you're point is that driving a car is dangerous, I agree. If
you're trying to make some analogous connection to flying a plane at
it's service ceiling, you missed the boat (car, plane...).

Little notice from a German "Autobahn" driver:
I had a Alfa Romeo where I felt very comfortable even with 150 mph
and I had a Jaguar where 120mph was nice but at 150mph I had the
impression to became instable.
I pushed a Chevy Blazer to 100 mph and was afraid to kill myself.
Everything is relative , some dudes manage to flip over at 30mph , I
have seen this last December here in Dallas, and with the right car and
environment even 200 mph are safe.

Sorry way OT.
