This is a case of flawed logic.
While this may sound reasonable, most accidents on freeways are caused by two vehicles going different speeds. Sure, a kinetic limit would reduce impact energy, but at the cost of increased accident rates.
Ok, hear me out⦠we should abolish speed limits on roads.
But replace them with limits on kinetic energy.
Β½mvΒ²
Half the weight means you are allowed to go β2 times faster.
Honda civic can go 50kph, bicycle 200kph, Ford pickup 30kph.
All have same energy when colliding.
