Early 90s me, with my first car, a 90 MR2, did a suitably cheesy 90s mod (I don’t remember exactly what, but it was something really tacky like taillight louvers or such.)

I was in the garage, and put the car in reverse with the ebrake up to ensure the reverse light was still bright enough (yeah yeah it was an auto, I was a kid.)

As I was admiring my handiwork, the ebrake failed. With the drivers door open. With a garage support pole right in the path of the door.

The car crept backwards, the door crunched on the pole, and got totally mangled.

I still remember idiot me trying to stop the car from moving by pushing on it.
