Starting with pulling on the door is already impolite imo. If there is no visual cue as to the occupancy of the room, then the first thing one should do is knock. If the light is off or the occupancy signal says it’s free, then sure, try the handle. Otherwise knock first, give the person who is shitting there a chance to reply with “occupied” or to knock back. But looking through gaps or trying if the door opens with the handle and then going “oops sorry”, please no.
Same goes up for offices, meeting spaces, bedrooms etc, when the door is closed and it could be occupied, always knock before attempting to enter. Less bad when someone does it, but still, one could just knock.
FYI, some numbers. The guardian article is still definitely worth reading, it just had no statistics.
*Nationally (USA), Tesla drivers had 26.67 accidents per 1,000 drivers. This was up from 23.54 last year.
The Ram and Subaru brands were again among the most accident-prone. Ram had 23.15 per 1,000 drivers while Subaru had 22.89.

As of October 2024, there have been hundreds of documented nonfatal incidents involving Autopilot and fifty-one reported fatalities, forty-four of which NHTSA investigations or expert testimony later verified and two that NHTSA’s Office of Defect Investigations verified as happening during the engagement of Full Self-Driving (FSD).*
