The car industry should have cars go no more than 60 mph. The Police, firemen and emergency vehicles should be allowed to have higher mph on their cars. Why is the car industry allowed to make cars go almost 100 mph? There would not be any temptation to speed since the car can't go over a certain mph (60 mph). I believe it's about money. Cars have the option to speed close to 90-100 mph. If we remove this option, even most people would never go over 70 mph, it might reduce sales on cars. I am not sure about this theory.
