That's the natural order of things, don't matter whether you get plumber, doctor, lawyer, upholsterer, mechanic..............it's all the luck of the draw, but at least with impaired driving YOU have the ultimate control by not drinking.
I rarely drink and never drink and drive. I have a class 1 license and cannot afford to lose it even for a day. The point is that those enforcing the law should also have to follow the law and not bypass our constitutional right to due process.
