“..why don’t they just go for a truck that drives itself..”
It looks like they are. I’d say this is a design that takes autopilot into account. I’m thinking full load in a wreck and carbon fiber in place of steel. After a few no one will want to drive them but google.
I admit I am over snarky but center wheel driving seems like it would be more than distracting considering the way most people are used to driving and will still be driving even if you are the only one driving this newfangled vehicle.
As a casual question why did the original car makers up and through a century of development NOT exploit this?
