SXE10 thrust angle

Got out I for test driving of SXE10 TOYOTA Altezza after the thrust angle adjustment, as the frontal alignments had been established few days ago. Only 0,60mm external movement of rear toe adjusting linkage rod eliminated the chronic wondering disease thoroughly. As for my surprise, almost I was about to make a rear-end collision on the highway, becoming very sleepy especially if the conditions are overlap, a vehicle with good wheel alignment and after lunch. It's often the case that a well aligned automobile induces sleep, because the reduction frequency on steering adjustment while cruising leads to distraction of concentration.
I wanna put an emphasis on this point that the only disadvantage of establishing the precise wheel alignment is "Induction of Sleep!". We cannot be too careful not to fall into "Sleep" while driving an automobile specially well adjusted one.
