Indeed. I read this
"This is a public street. You're not expecting privacy on a public street."
and my immediate reaction was "then perhaps you should be".
You aren't expecting not to have your car seen by someone passing in the street who wouldn't give it a second glance or remember it 10 seconds later. However, that's a totally different thing to having its identity and location digitally scanned, recorded indefinitely, and searchable in combination with arbitrary other data sources, giving rise to the reasonable privacy concerns mentioned in TFS and many more.
And don't forget, that the scanners read everything within their field of vision... so they will also collect information for vehicles sitting on the driveway as well as in the garage, if the door is up.
