I-80 is definitely a hotbed of aggressively dangerous driving and the violent use of vehicles against others that aren't driving how you want them to (and I'm a fast driver).
Have those two experiences very much back to back, I joked about how once we get robo-taxis we'll never go back. Human drivers are dangerous enough of the time -- it's not like I've ever driven on I-80 and NOT seen crazy, pants- staining driving. It's every mile or two of the whole stretch.
(Waymo feels so much more mature and pleasant than the last FSD Beta I tested.. Elon should be embarassed.)
