Not really more expensive. If we have x deaths per year..let's say 10k for easy math. Over a decade that's 100k people dead. If self-driving cars can bring that to 0..that's 100k more people in a decade able to pay taxes because they didn't die. It's 100k families that maybe didn't lose their primary bread-winner and don't need to live off government assistance... So there's economic value in less people dying. It's also less in medical costs. Imagine what the bill for medicare for all would be if there were 0 traffic accidents across the entire U.S.A? Not to mention it could ease up congestion and make changes to the way they do construction or how often by maximizing speed and travel to make roads last longer somehow... Also less need for police to monitor traffic, I'm sure we get that sort of grid we'd also have a lot more big brother surveillance baked in too to make police jobs easier. Which I guess is good/bad depending on which side of the privacy ethics you are on surveillance and how 'honorable' our government is at the time (hopefully more honorable and less like china and it currently is)....
