identify - maybe, prove it at the court of law - somewhere between hard and impossible.

say you have found all these "not that many" cars, and now what? you would have (may slightly depend on the local law) prove who is the driver. that may be impossible, even if you have photo of the driver and photo of the suspected owner and you "think" they match.

the car also doesn't have to be local, whatever your threshold for what local is is.
