I actually I heard that reginald denny has been driving an ice cream truck nowadays, looking for a little payback.
Sorry, that was in bad taste I know.
Seriously, he may not have survived.
Or good chance he survived with serious maybe permanent injury.
It looked like the main impact was to the upper torso.
That kind of impact can force ribs into the lungs , heart or other fatal areas, crush organs and majors veins and arteries, break the spine/neck..........basically kill or paralyze you.
What he was doing was dumb but everyone gets dumb sometimes.
Hope he isn't hurt too bad.
