Realistically though, I agree with your sentiment. Solving this would drones would require a constant flock of something more akin to Predator drones.
The better question is - why do we allow high speed pursuit chases in the first place?
Rather than some inherent sized for safety idea.
Jamming might be interesting, I suspect that it's easy enough (and a much bigger crime) to follow a very loud jamming signal though.
Every practical metric a drone surpasses a helicopter; they are so much simpler to operate that you can easily offset any perceived downside with more drones. And you don't get a tested solution without trying it out.
AFAIK they've changed their tactics in recent years, but growing up around LA these we're like sporting events on TV. It's a guilty pleasure, but almost everyone I know tuned-in and watched the chase.
But people love ‘em, and if you point out what a bad idea they are people label you “soft on crime” (as happens with a lot of plainly good policy)
