At least where I live that's where people usually put their dogs. With sedans and SUVs it's not as cramped though and often there's a transport cage for them.
frame snapped when he tried towing an f series pickup
in a later video he made sure to beat on the f series, and while the frame did bend, it wasn't a sudden catastrophic failure
a quick summary from some website
The F-150's steel frame didn't break, but bent under extreme abuse - unlike the Cybertruck's catastrophic failure.
The Cybertruck's aluminum frame is unfixable after being torn apart - unlike the F-150 which can be repaired or replaced easily.
Despite the haters, WhistlinDiesel's extreme testing proved the F-150's durability, while the Cybertruck suffered irreparable damage
Credit where it's due, the Cybertruck took an absurd fucking beating before it died, and its clearly quite safe from outside intrusion to a pretty extreme degree. That frame snapping was kinda insane though, I can't really put into words just how much that shouldn't be possible.
And in a later video, he showed a photo and chat with a viewer. They saw someone's Cyertruck's frame snap off while hauling a trailer which hit a bump on the highway and sent the pic in.
