Losing consciousness while driving?

Losing consciousness while driving an automobile is very dangerous for safety traffics, if the lost period of may be quite a short moment. Once famous NHK announcer said he never drive a car by himself because of unintentional habit to lose self consciousness for short period of time leading to some serious traffic accident.

I have often experienced this kind of situation especially after attaining the precise wheel alignment and geometric axle construction correction.
The adjusted automobile goes straight like an arrow without any specific concentration to keep the center of the lane.

No changing phenomena of nose direction occurs being influenced by the ground inclination may happen, just the steering tells the change of ground line by giving some pressure on the steering wheel. So, the efforts required to keep straight running is just holding the steering wheel at the centric position. No efforts nor concentration are necessary on earth.

This is why the completed automobile on wheel alignments has a tendency to invite the dangerous phenomena of losing consciousness while driving an automobile unintentionally! Here I wanna put an emphasis on the point that the phenomena of losing consciousness resembles that of sleeping while driving, but different ones each other.

Recently have I some suspicion on the precise adjustment on wheel alignment and constructive axle geometry correction, they would not always give a automobile driver only some benefit but also some danger of a traffic accident caused by driver's losing consciousness.
In another words, some concentration and efforts to keep the automobile run straight may be necessary not to lose own consciousness of the driver?

The more precisely the automobile was adjusted on wheel alignment and geometric construction, the less concentration is required to keep the car run straight. So the possibility to lose consciousness increases leading to a dangerous traffic accident?
