the overall increase helps you indeed. But do you want use self-driving software if you are a great driver(or you think you are)? I do not because I want to be more safer by driving myself.
If great drivers like to drive themselves. Others wants too because they do not trust these great drivers.
In everyone driver's eyes, there are only two kinds of drivers
1 ) bad driver slower than me.
2 ) mad driver faster than me.
Consider you are a damn good driver, better than self-driving software. If self-driving software can reduce your risk by giving you a safer environment(by replacing lots of bad drivers), but it will increase your risk when handling risks(because it's not as good as you). Would you like to choose self-driving software?
The point here is, no matter how good the driving environment goes, I do not want to lost any chance to survive(If I'm a good driver).
Self-driving car could be better than human in average. But as long as there are human drivers who drive better than self-driving software, it would be disaster for these drivers. We definitely do not want some technique than do good for majority but do horrible things for minority, right?
