This is a disengenous comparison.

The overwhelming majority of people who fall from 30ft do not attempt to decelerate in the last second or so.

People who text their way into stopped traffic notwithstanding, 30mph is the kind of collision speed you see on roads where traffic moves low highway speeds. Edge cases notwithstanding (i.e. someone barreling through a red or whatever) collisions on roads where traffic moves 30-40 typically happen at speeds 10-20mph below that because people generally brake but too late to prevent a crash.

Changes quite a bit with getting sideswiped while walking around the roadway, my #1 fear as a pedestrian. Looked up some statistics and this is more common than getting hit while crossing the street. Two more things to figure out though:

- How often is an accident while walking along the roadway getting sideswiped, instead of just a full-on crash

- The equivalent of being run over by a car doesn't happen when falling 30 feet. I wonder how much this accounts for getting hurt as a pedestrian.

This is just what I thought of, it is also a threat to cars, but that would be offset more by the velocity of the car that got hit than it would be by the velocity of a pedestrian. (For example, a car that is going 25mph and gets rear-ended by a car going 30mph)

Also there is often hitting the brakes before collision. So it will be slower sometimes.

That's a pretty great way to visualize the energy involved
