I would like to know if current advanced safety tech such as lane centering and collision avoidance significantly cuts down on highway deaths due to driving impairment? Since these technologies are already starting to become standard, once they get more reliable would that itself make accidents plummet? I'm not talking about full self driving, but just the currently available assistance technologies that work 95% of the time (and if they improve to work 99.9999% of the time).
