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.
