A driving hazard revisited

TLDR: John Baylis considered the following problem: When making a right hand turn on British roadways one moves as far to the right as possible on one's side of the roadway and then turns, but the rear of the vehicle moves leftward as the right handturn is begun-toward the unsuspecting driver passing on the left.

Abstract: John Baylis [1] considered the following problem: When making a right hand turn on British roadways one moves as far to the right as possible on one's side of the roadway and then turns. Unfortunately, the rear of the vehicle moves leftward as the right hand turn is begun-toward the unsuspecting driver passing on the left. This can be quite noticeable if the turning vehicle is a long bus. We assume familiarity with Baylis's paper and notation. Recall that he defines I = length of wheelbase, h = length of rear overhang, 0 = angle between bus and direction of roadway, 0 = angle of front wheels relative to the bus, V = speed of the bus.
