I think everyone has done something like that. I locked myself out of the new car, and it was starting to rain. Would have not been too bad but the top was down...:drum:
On the _real_ side, having all windows open allows you to hear, and see better. Also turn off the radio, never know when / if someone else on the ramp may do something dumb, or someone may slip, etc. Being able to hear others could save a life or prevent bad injury. I have seen some pretty stupid antics on the ramp by others, who have zero comprhension of what is going on or who is doing what. One guy went behind my backing up boat and trailer about 2 weeks ago - IN THE WATER.. He slipped and fell on the slick algae. I saw him as he was scrambling to swim out of the way.
On my boat, I can have premature self launch. I dont undo the safety chain till the back end of the boat is far enough in the water to float the boat. Then a short 5 foot back - hard stop! and she is in the water. Makes solo launch a piece of cake, but an unsuspecting ( or stupid! ) person could end up in a bad place.
Cheers!
