I've mentioned it before on this forum, but before I was a software developer I spent over 10 years as a land surveyor. I mention that because it involves a lot of road layout and roadside work setting control points, &c. I used to find so many empty flasks of booze, empty syringes, and empty pill bottles in the weeds on the side of the road that drivers had thrown out the windows of their vehicles. Even in some rural areas this was the case. The point is that there's still a lot of Americans driving impaired. There's a certain amount of risk involved in operating or riding in a vehicle even if you are stone cold sober. You never know if other drivers are impaired until it's too late.
