Well, if you could transform your problem into the "stop" vs. "ped x-ing" problem, you could let the future smart self-driving cars solve it for you. Maybe they have more computational resources than you can muster (but that sounds very contrived, even if you could somehow harness the computational power of a freeway full of future cars). Or you could imagine another very contrived case where some self-driving car company controls some important algorithm you need to solve your problem via a patent and it would be illegal to solve your problem otherwise (also very contrived...).
