This is your reminder that the ‘park’ state of a transmission is just a small pawl that is pushed into one of the gears. On uneven surfaces and/or with sufficient force the pawl can simply slip off the gear (or just break) and allow the vehicle to roll.
With electronic parking brakes on modern cars, i wonder if they can’t be applied automagically after a few seconds of the vehicle being in park.
This is not an issue manual transmissions have, btw.
I bet anti-natalism grows as a movement going forward.
