I need help with bringing up a certain topic with my T.

Yesterday, I saw my T for the first time in four months. It was a great session and I'm glad it's currently possible here to see him.
During the session as well as during a few previous phone calls, he mentioned that he's taking his car to get to work for now. It's normally a pain to drive cars in cities here and public transport is used a lot, but he (as well as a lot of other people) think it's currently safer to take the car as often as possible.

In front of his office, there's two parking spots for people attending therapy sessions. I noticed that there was one car that's normally never there, Fridays are usually not busy at all in his practice and I'm often the only person there, which was also the case yesterday. The car really fits what I'd imagine my T to drive. I didn't mention it yesterday since I don't really care too much, I was just glad to see him.

However, it later occurred to me that my T is probably not aware of the following: in my country, our DMV runs a website where you can enter basically any license plate number and find out who owns that number, as well as where they live. My T is pretty bad with technology and the internet (he once told me he found out about google 'a couple of years ago', when it's been out for much longer than that, I had to tell him how to write certain characters in our language on the keyboard, he didn't offer video sessions because it was too difficult for him to figure out how to set it up...). I am almost 100 percent sure he is not aware of the fact that such a website exists and that it's that easy and legal to look up the address of somebody given their license plate number.

I know that he values his privacy and that it's not easy, if at all possible, to find his address via google searches (I've never researched it in depth, but it's certainly not something that just pops up if you google him, it's not in the directory or anything like that). I'm not sure it's his car, since I didn't check that website and I don't plan on doing so, I feel it would not be good for me to know such information (I've had trouble with learning way too much about people in the past, that's also how I know this website exists). I would, however, like to point out that if this is his car, then all his clients who pay some attention to their surroundings could figure out where he lives.

I'm not sure how to best go about telling him. I feel that if I say 'I saw this car, it looks exactly like what you'd drive and by the way, it's possible to figure out where you live from that', he will think that I actually did look up where he lives if it's his car. And in that case he would probably be angry and while I doubt he'd terminate me, it's something I'm always scared of so I worry about that a lot.

Do you guys have any idea on how to best breach that topic?
