A 40 tonne truck traveling at 100 kph produces the same force in a crash as a 2 tonne car traveling at 1,008 kph. (The formula for force is a half times mass times velocity squared divided by stopping distance.) I am assuming the stopping distance (amount of crumpling) for the truck is 0.1m and the stopping distance (amount of crumpling) for the car is 0.5m. Cars don't travel that fast of course.
I think we need more divided roads and more rail freight.
