I hide the things in the back of my estate car with a tonneau cover.

The suspicion (which would need to be confirmed by investigation) is 
that the invisible driver of a car with heavily tinted windows is doing 
things like illegally using their mobile phone.

And in the rare circumstances you were looking for a particular 
perpetrator, you'd need to get them to stop; whereas lone grannies with 
clear windows would obviously not be the car full of teenage thieves you 
were looking for.
