Also 140-160 km/h aren't normal highway speed. They are in fact illegal in almost all countries.

Speed limits are just glorified toll boots made to extract revenue from people with powerful cars.
Also manufacturers are moving away from providing 200km/h+ capable cars. Volvo is pioneering this citing safety concerns.
140 km/h and above is not a normal highway speed in any country except Germany and even there it is not really that common. I returned from the UK to Norway last week. It was about 26 hours of driving through France, Belgium, Netherlands, Germany, Denmark, the amount of time I spent at more than 130 was just a couple of hours.
And of course the vast bulk of traffic on the roads is very much slower. Also quite a lot of ICE cars are not built for sustained driving at high speeds anyway.
