Oh yeah, great idea.
What are you going to arm it with once someone decides to toss it in a suitcase and drive off with it?
Now dropping the tacos from 50 feet up with the stipulation, “you miss it, too freaking bad” would be interesting.
Parachute drops would sound reasonable. Why only tacos? Why not a full fast-food menu?
That turns it into a sport. Likely a government grant would be forthcoming.
Kid: "They're dropping tacos!"
