Compared to the 'bus, the Boeings do it on a neglectable scale, hardly noticeable on Radar.
Even when flying towards an obtuse angle, the 'bus will turn (depending on angle and speed) several miles before the waypoint to "catch" the next track.
When it gets really annoying is when the angle between tracks is acute, then the turn can "happen" up to 15NM before the waypoint. Not good and safe enough!
