Yaas. Intellectually, I knew that the tech was available, but I've never seen it in use before.

It's possible that they're just scanning and correlating the plates, but now I'm left wondering how much data lookup and recording they're actually doing. My bet is that this is a security feature, not a convenience one, which implies that they're probably logging all entrances and exits. (And I do wonder what they do if you have, eg, a plate that's too dirty to scan...)
