The point with impaired driving is that car dependent infrastructure is the problem. Plenty of drivers use Uber or cabs when impaired. When you have millions of drivers going through intersections like the one pictured with no feasible alternative, deadly crashes are going to happen.

Unless we fix the mandatory car ownership prevalent in most of North America, it really should be treated as almost a right. How else are people going to realistically safely get where the need to go?
