Because fire. Because lots of twisted metal.
It was an unusual experiment, to the say the least. But it's still a hell of a publicity stunt. Yep, we're taking the bait because anything involving watching a truck getting demolished is hugely entertaining. The idea here was pretty simple: destroy a truck through various methods (of course fire is involved) in order to see if a group of technicians have the skill to put the thing back together in only 24 hours. Really, this was actually done.
The video ahead was made by Ryder Fleet Management Services, and we get the point pretty clearly: truck destruction caught on video is wicked cool.
