just found out that tesla has an option on their new cars to make the car drive autonomously right now, this year available right now. it says you can drive up to where you want to go, get out, close the door, and the car will drive itself through the parking lot looking for an open spot, park itself and wait until you call it with your cell phone at which point it'll drive itself to you to pick you up
I have a pair of jeans with buttons for a fly instead of zip. It's impossible to get it open, and they are quite a tight fit at the waist so pulling my fella out is also hard. So when wearing those jeans I have been known to pull them down to like my knees. Never in a public toilet tho..
