I've noticed it too. It seems like half the drivers on the highway think they're in a video game, routinely passing on the right even when the passing lane is open, using any and every lane to pass, slipping in between cars with only inches to spare, tailgating even at close to 80 mph. It's terrifying.
I fully expect to see the car performing such maneuvers flip in the near future.
Some of the newer cars might as well just have a joystick (if your old school) or an Xbox console controller. Difference is you don’t get 3 lives. Only Mario does.
