Why anyone needs a car that does 155 mph or a roof rack good for 140 mph

Well, you do need it if your shoe size is small.

There are many parts of the PA Turnpike that would be perfectly safe at 100 MPH if that were the legal limit. Obviously not around Philadelphia or Pittsburgh.
The issue with raising the speed past 70 is there is a LOT of big rig traffic and many of them can't even maintain 70 up the hills.
Also, cruising at 100 in a Tesla almost guarantees you'll have to stop at every Supercharger, it really gobbles electrons compared to cruising at 70 or 75.

It is many magnitudes harder to drive at 155 than 100.
I used to spend hours at 100.
125? enough , I have never been over that.

There are lots of deserts in California with straight roads where you can drive 155. But I rarely go above 100 in the LA area where I live.
