People who really need pickup trucks might be happy to have them painted in dirt colours with no speed stripes. I'd also like to see mud streaks (from creek crossings) on SUVs with snorkel air intakes.

Yeah, seeing a snorkel is pretty rare.
I just want to clear up something. There is a strong belief at work that the immense popularity of trucks in the 1990's stemmed from people wanting body on frame, rear wheel drive vehicles. Almost all cars at the time were front wheel drive unibody or body-frame integral. And car sales sucked. (4wheel drive was just about status, mostly).
Frames add weight and height to vehicles but make them strong.
In order to make those numbers they're talking, the frames gotta go and the vehicle must get closer to the ground for better aerodynamics. No more truck.
So when Detroit rolls out their El Camino looking pick ups its gonna be a shock. Especially when they find can't haul anything.
Good night.

Here in the SW USA, that would encourage more drivers to ford the flashflood. Hmmm... it would give Darwin a better chance to work. Yeah, I think snorkels could be EROEI positive (by getting idiots off the road) heh, heh.
