You guys at US have this kind of service:
Road Hero
Here such is not possible as such databases of registration plates must not made public and are treated same as social security numbers by law, our nannying country again.
Police cars here too make such of stunts sometimes, once I was travelling with seriously overweight trailer and van combo at middle of night, going as fast as that combo did go, which was only tiny bit faster than legal limit, I did saw lights appear behind me on very long straight, I did estimate that it was over a mile behind me, it did not took long that police van zoomed past me really really fast, could hear turbo whine as it flew past me, thing sounded more of jet plane really, it was followed by sedan model police car which are here bit of rarity to see, there still was more than a mile of that straight left but they did disappear from sight really quickly. I think speeds were more than 100mph, no flashing lights, no sirens.
