We came close to that back in the 80s, when by government edict, speedometers stopped at 85. The theory was that there's no incentive to go faster if you don't have the actual number to brag about at the bar. Proposals were floated to put governors on cars, but it never came to pass.
“We came close to that back in the 80s, when by government edict, speedometers stopped at 85.”
I didn’t know that, as I was overseas for most of the 80s.
I just figured crap American 1980s cars wouldn’t go any faster.
