Car driver was very strange and creepy

I’m a bit weary about posting this. I recently had a very “senior “ aged male driving me to a doctor appointment. This ride was about an hour and a half each way. He started talking about his entire life and started driving in the city on all of these side streets etc. At first I didn’t care but then he started talking about his lifetime career as a cop and telling me all about working the sexual orientated business areas in the city and how the men in drag all had “heavy equipment “ and sure seemed ok to talk about that. He took the backroads home and made multiple stops and they aren’t supposed to be said. He took me site seeing etc. Lastly, as I was getting dropped off at home he told me he noticed I wore a bra this time because several years ago he took me twice and didn’t think I owned a bra. Next day, he’s calling my cell phone and I didn’t answer. Later that same afternoon he called again. Left a voicemail but nothing specific. I go on Facebook and he shows up on “people I might know”. Really? And 75 or 80 year old man? I blocked his number on my phone. My Facebook is all private and the crazy part is I don’t use my entire real name for Facebook. He did ask what my mothers name was during the trip. So he must have went to her public Facebook and searched for me on her friends list. I haven’t complained to the company because I think it might make him act out. I just don’t know. It’s so disgusting.
