Should I expect a ticket in the mail?

I believe there was a undercover cop on my tail for a while.

Some things that may be wrong is, I have a bike rack on my trunk and it sorta blocks the licence plate. But even if I put my bike on the rack it will block it any how.

2nd thing is I accelerated fast, and hit the curb. I was speeding a tad bit.

I think it was undercover because of his unique blue licence plate, ford, and it looks like he was wearing a uniform. Plus tailing me for 10 min+

I guess he let me go? Because he stopped following me after a while.

Stop beating the dead horse!

Probably.
