Methinks Barry was being funny and was joking with you, as you stated you were using it to see people, instead of vehicles.
I have one mounted in my rear window of my trailer. It is VERY useful to have so you can see what is behind you, especially in your blind spots before attempting a lane change, which you will do a lot on interstate.
You have the right idea.
