That would've been hilarious. Imagine them in the car, doing their business, then they hear a loud buzzing sound, look out the window and "HOLY **** WHAT'S THAT?!"
In that case, you would still need a drone operator I would think. So, the angry husband would go after the drone operator then. In this case, I guess it would be himself. The drone is a victim and might need counseling....or at least a thorough cleaning.
When drones do start having sex, it makes you wonder what the coverage of that is going to look like given you will have two different POV's, and possibly additional drove coverage from a third or more. And if the male drone falls asleep afterward, does it just fall out of the sky or what?
