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.
But what I was trying to describe is a "mild mannered" getaway driver. Not fleeing from cops, not speeding. Just calmly driving to and from crimes. Should we punish the road makers for enabling such nefarious activity?
(it's a rhetorical question; I'm just trying to clarify the point)
It's a stretched metaphor at this point, but I hope that makes sense (:
