2002-03-05 The use of the metre per second as you describe is brilliant. It would be a great idea for all cars to have dual scales, kilometres per hour for long distance driving, and metres per second for brake and manoeuvre time. And if all cars had to have both scales by law, then it would be impossible to add the FFU on them.
