E = mc^2. The bigger the vehicle the more mass the more force and time needed to come to a safe stop. More force on impact to the driver and pedestrians.

- causality0 4y agoI believe you mean e=1/2mv^2. Einstein's mass-energy equivence formula doesn't have much to do with the kinetic energy of being hit by a truck.
- brucethemoose2 4y agoUnless the truck is fast enough to spontaneously trigger nuclear reactions. Or fast enough to have a nontrivial mass from pure kinetic energy (though I think the nuclear reactions would start happening well before then).

- dtgriscom 4y agoBig does not have to mean slow to stop; you just have bigger brakes (and since they're power, the force doesn't matter). Once the vehicle::pedestrian mass is high enough, a higher ratio won't change the kinematics much. And how are you thinking that a driver of a big vehicle is more at risk than that of a small one? And, Einstein has nothing to do with it.
