Last time I was in Texas, it was legal to drive 80 miles an hour on certain highways.

If you needed to make a u-turn while driving on the highway, you could pull into special areas in the median of highways to make those turns. The same places highway patrol often use to sit, wait, and monitor traffic.

Both of those things are illegal in Virginia.

I don't remember what the exact number was (maybe 75mph) but I had a rental for a business trip out west somewhere--maybe Arizona--and it turned out the car had a governor set to whatever the number was--which at the time was presumably significantly over a lot of speed limits but was right at the speed limit where I was driving. It was very annoying as the car would suddenly drop the throttle and slow down. Only time I've ever seen that though there may be governors set to speeds I just don't hit in other cases.

There is a gentleman's agreement between many manufacturers of street legal cars to produce vehicles that will not accelerate to faster than 120-130mph unless some special conditions or limits are met.

Been that way for at least a decade.

Speeds within many highway speed limits (like 75mph) are not 120-130mph however.

Not all laws are best enforced by manufacturer collusion. I assure, if you want an corporate oligopoly, that's the way to go about it.

Make things. Let people figure out how to use them. Keep semiconductors neutral.
