This needs to be updated.
Getting hit by a pickup truck at 30 MPH is similar to getting hit by a Honda Civic at 120 MPH for kinetic energy.
That’s besides the fact that pickups have a much taller hood vs sedans so there are significantly higher rates of head injury.
Taller cars and trucks are more dangerous for pedestrians, according to crash data
Your math is wrong. Kinetic energy scales linearly with mass, quadratically with speed. The graphic you included supports the idea that at same speed, the pickup truck has double the KE. The 120 mph sedan has dramatically more KE than a 30 mph pickup.
Assuming that your sedan has exactly half the mass of the pickup, it would match a 30 mph pickup’s KE at 30*sqrt(2) mph, which is somewhere between 40 and 45 mph.
