I was driving 45 in a construction zone. Someone behind me was very close on my bumper, obviously in a hurry. After the construction ended, I moved over. The person behind me flashed their lights at me and then passed me once I was in the other lane. Five minutes later, I received a random text that said "Do you think you can do 55?" By the time I received the text, the person was out of sight.
My question: Is there technology out there that could allow someone to find my signal and capture my number?
I have a theory that if the car was associated with a state/government agency, the person driving could have ran my plates to get my number.
Any thoughts? Thanks.
