OMG! I do this too :(
Isn't it crazy how many precautions we have to take as women?
I was reading your story and, despite I don't check the trunk or send the Uber's plate to anyone, I was feeling like you were talking about me!
It's sad and frustrating that so many people don't see how wrong is being cat-called. The worse part is that it's ok for some women too, one of may girl friend said I was overreacting when the security guy working at a local store asked my number out of the blue while I was exiting the store. Just Unbelievable.
You are right, it's time for this issue to end!
