Can’t you make patterns in infrared reflective paint?
Here comes the sun, do do do do
No need, you can just use an IR spotlight to blind the camera. Unlike the military you're not trying to hide the vehicle.
But either way you're actively trying to avoid being picked up by speed cameras so you get a fine.
This isn't about speed cameras, it's about "safety" surveillance cameras. No laws have to be broken. Evading Flock isn't illegal

Not really. We don't have materials that absorb or reflect infrared light. It's one of the reasons it's hard to beat inferred-guided (heat seeking) missiles, the only real solution is to drop something hotter than your plane, aka a flare.
So... get ready for a new era of commercial automotive flares I guess?
You are mixing different types of IR and on top are wrong for both cases too. We have materials for both NIR and thermal IR that absorb or reflect them.
I've been wrong before, this wouldn't be the first time. But what part of it was wrong? Genuinely, can you clear it up?
As far as absorbing IR light, I'm not even sure how that would work, wouldn't it just be emitted again as heat?
What if I just hold a sparkler out my window?
