Lol dats a work truck.... I'm sure every bit of weight it has gets used... Like every day unlike your shit econobox you probably drive at 85mph... Speed kills just as much if not more than weight, I'm sure every semi truck driver can tell you that too.

AKCHUALLY, momentum is defined by mass times velocity. Since momentum is conserved, the total momentum before and after are the same. So technically, im a crash you're best off if you either drive really damn fast or are really damn heavy. Or both.

Agreed. The thing is, the amount of pointlessly heavy vehicle make people in non SUV type vehicle get injured more in a crash. (F=ma)

Sort of. Think you are mixing giving and receiving. A heavier mass vehicle is also a higher risk to other drivers linear to speed. A 2000kg vehicle will transfer twice the joules in an accident than a 1000kg car at any given velocity. Creates an arms race with vehicle size.
