I wouldn't cause of how extremely painful it'd be to be crushed under tires smearing your body and guts all across the pavement like a bug. There's no guarantee that the way you jump under or in front of the truck that'll kill you instantly. Besides burning alive this is my biggest no no cause the pain would be unimaginable. Plus I'd say it would scar the drivers life and the people who see your corpse cause of how bloody and brutal it is. Look on ync and find a video of the act, it's not pretty.
