Yes, but traction on pavement is quite a bit different than traction in mud on a 20deg slope with a Really Heavy Vehicle. There are varying degrees of "uniqueness". My point, which I think you deliberately "missed", is that looking at it from the "layman's perspective" is flawed. (And lane tracking is generally more forgiving than row tracking, (except for on the Garden State Parkway) in the sense that a few inch deviation while driving is acceptable, but cumulative parallel row error can add up to quite a bit, both time and money.)
