I hope that people driving 140 km/h are more focused on driving then I am. Driving 100 km/h in normal conditions in Spain I barely have to overtake any cars. I have to be aware of what’s more than 100 m in front of me most of the time because there’s simply nothing closer. Driving at 120+ km/h you overtake all the time, you drive way closer behind other cars and you have to check mirrors all the time. So there’s different level of focus required at higher speeds.
