With a good wheel alignment, a vehicle will track a straight line "hands off" for quite a distance. Just don't try to shift in the middle of a turn. The 1958 Mack B-73 that I learned to drive big rigs with had two shifters. We spent quite a bit of time shifting with both hands. (without using the clutch, BTW) No, we DID NOT stick an arm through the steering wheel- - - -an unexpected bump could make the wheel spin and break something!
