Sounds like you were on the same speed awareness course as myself. Either that or you were the guy running it.Bear in mind that if 2 identical cars are travelling on a motorway, but one is doing 70mph and one is doing 100mph. Both brake hard at the same time with the same force. When the car that was doing 70mph comes to a complete stop, the car that was doing 100mph is still going at 71mph and has travelled much further.
Food for thought.
