I don't drive yet but when I'm practice driving going north which is not a busy highway, I go 50mph. My husband usually go on 60-70mph and sometimes when we enjoy our talk he go 50mph and I grumble lol, slow driving make me feel sleepy. Yesterday I took the bus home in the afternoon and its so slow that make me fall asleep.
I'm thinking about this new LAW that they are trying to implement again to save 2% of gas each drive you make and the speed limit is down to 45-50mph. I'm wondering because me as not an expert driver yet find it slow what more to those Pro drivers, it will make them sleep and might cause ACCIDENT. Yes you save gas though but make sure to fuel up with extra dark coffee lol.
