As someone who grew up doing a lot of outdoor activity, I assumed part of the fun of owning a drone and/or motorboat was annoying the shit out of the people around you?

My family cottage is on a lake about 4km end to end. It’s the perfect size for some water skiing, tubing, swimming, fishing. But some maniac has one of those boats with four outboard engines lined up and zips across it in seconds. Insanely loud. Just awful.
