I don't see it being that dangerous. He's likely just pushing it slightly open with his left forearm automatically and taking his eyes off the road just for the second he needs to spit his tobacco out. If something happens the moment he stops actively pushing the wind will close it and he's likely strapped with a seatbelt so it's not like he can somehow fall out. I've had to re-close my door at speed multiple times on old vehicles because I didn't close it hard enough and it was never sketchy in any way. Doing literally anything on a touchscreen takes more attention. And the documented part is BS. People don't read their owners manuals and even if they did it'd usually say not to open the door in motion, not that it will slam the brakes if you do. Even if it does it's unrealistic to expect people to read the manual of every car they drive. Rentals would go out of business real quick.
