Level 5 will require V2X infrastructure. We will get there eventually most likely 203x. Might need dedicated lanes to start and then eventually only level 5 highways. Similar to how we transitioned from horses to cars and eventually figured out they cant really coexist on the same roads.
Wind noise is noticeable at around 70 mph in my Gen 2 R1T. Got a screw embedded in mine in the first week. Discount tire removed it. No leak. Didn't need repair. Definitely going back there for my Rivian tire needs.
