@Cyberpower678 , I'm not sure I'm getting what point you're trying to make. Seems to be that cars
can be far more lethal and dangerous than drones. If so, then, so what? Seems to be a completely irrelevant point to the subject at hand, which is about risk, not what is possible.
Again, I really don't see what important, relevant point you're trying to make here. It seems that you're trying to imply that, because cars can be misused in far more dangerous ways, there's nothing to worry about with drones flying close to cars on bridges, roads, etc. After all, the risk is trivial compared to cars.
Is that what you're trying to say?
As for the "car stopping by itself with mechanical failure", I'll ignore that idiocy. I assume you are an adult with sufficient experience operating a motor vehicle to understand
exactly what I meant, and it wasn't that.
