We really want to be able to have cars avoid obstacles on the road whether or not those obstacles are cars or not. And given how infrequently firetrucks are replaced we shouldn't expect that even if every new vehicle had this technology it wouldn't have made a difference anytime soon. And given the inherent security vulnerabilities of the technology, I'd expect that it would be a net negative to road safety by the time it had any substantial impact compared to the general progress of self driving cars getting better.
