Personally, I find it endlessly frustrating and even terrifying to be in the passenger seat with a driver who jumps in the car and immediately goes… Then worries about Seatbelts/Radio/AC/Mirrors/Plugging in Phone/etc etc while driving.
My father in law brakes incredibly late. Consequently, he brakes very hard. Drives me (heh) insane, and causes me to reach for the oh-shit bar and the ghost brake every time.
My ex gets distracted easily. She always hated that I would ghost brake, but I can’t help it when she’s not reacting to the stopped car in front of us
