Vehicle Inspections ... How About Driver Inspections!

While driving home yesterday, I ended up behind a car that was all over the road and ranging in speed from 15-50 MPH in a 35 MPH zone. I looked at the time, and figured the driver was probably on the way home from happy hour. Although quite entertaining to watch, the reality that this vehicle operator may harm someone other than themselves set in. At the next traffic light I pulled up next to the car expecting to find a prime DUI candidate, but was shocked when I found out that this driver was completely sober ... just a really but driver. The man was about eighty-five years old, couldn't hear a thing, and from the look of the Coke bottle glasses couldn't see very well either. Everybody today is in such an uproar about drivers operating vehicles while intoxicated (and rightly so), but aren't drivers that cannot see or hear just as bad? After all, I don't know any machine operators that can successfully do their job without the fundamental criteria of visual and acoustical awareness. Almost all fifty states employ a mandatory annual vehicle road-worthiness/safety inspection, isn't it about time to make sure that people issued licenses to drive are in fact capable of safely doing so?
