I'm getting "random people think steel is better, so without further evidence here's a pickup made with steel".
Their intended message, whether true or not, would be transported way better if the bear smashed the other cage first.
Hopefully Ford comes back with an appropriate response - showing the aluminum cage being made out of solid aluminum and the 'steel' cage being made out of thin sheet steel that can be bent by hand, that sort of thing.
Chevy's campaign against the F150 hasn't been all that great. They were using nuclear subs before to tell people "our trucks are made out of the same steel as those". What good is that? A sub has to survive under hundreds of feet of water. Is a truck ever subject to those pressures? Is the truck's skin made out of plates as wide as the sub's?
