Smart roads have been attempted for years. Usually with some sort of antenna or wireless/light transmitter embedded in the road itself. The cost per mile was just too high. Far simpler to use what's already there with computer vision and map metadata. Now that cars have GPS, A-GPS, and RTK need to tailor roads for autonomous vehicles has been diminished.

> The cost per mile was just too high. That's why I specified "in large metropolitan areas". I can see that it's impractical to outfit anything outside dense cities with such beacons, but inside the city they could augment, if not replace autonomous driving systems. Or so I imagine. > GPS, A-GPS, and RTK Thanks for telling me about RTK, I did not know about this!
