If these roads had been designed differently, to naturally enforce the desired speeds, it would be a safer road in general and as a side effect be a less desirable getaway route.
Again I agree we're really stretching here, but there is a real common problem where badly designed roads don't just enable but encourage illegal and potentially unsafe driving. Wide, straight, flat roads are fast roads, no matter what the posted speed limit is. If you want low traffic speeds you need roads to be designed to be hostile to high speeds.
