Have you seen other people in a car wash? Park, reverse, drive but they start holding the brakes when the track pulls them along, leaving antennas up, not closing windows, opening fucking doors... A vast majority of the human population is some level of braindead.
Fuck me, I've seen someone pull up into a manual car wash bay, open all their doors, and wash the INSIDE of their car. This was not a washable interior like a Jeep Wrangler or something, it was a typical sedan with carpeted floors and cloth seats.
And these people (theoretically) are licensed to drive, right next to you.
