As to chosing FoMoCo, it's kind of a family thing, a reflex as much as a deliberate choice.
But, it's not pure reflex as my work requires travel, so, I'm in rentals pretty frequently. In the last eight weeks I'be been in a Jeep Compass, a Chevy Tahoe, a Toyota 4Runner, and even a Ford Edge.
Getting into that Toyota was bit like leaping into the Chariot without a briefing on the controls. Trying to decypher the cruise control at 0600 can be les-than ideal. (It's somewhat distressing to contemplate being more able to jump into an excavator and be more familiar with the controls.)
Which gets us, full circle, back to the interio of the Chariot. I'm not remembering how the sterring was depicted in the series. The SnoCats the Chariot is based upon have both wheel, tiller, and brake lever steering. The wheel and tiller sterring run much like a car, turn the control in the direction of wanted movement. With brake levers, you pull back on the side you want to be the inside of a curve. (On some venicles with clutch lever steering, you push forward, instead.)
Which steering system can affect how many and what sort of pedals are on the floor, too. From memory, SnoCats use a lever to set the acceleration, not a foot bedal.
