It'll be funny to have a secret switch, like covered with a center console sticker (self destruct would be cool) blow off a train horn in your Smart to a cop, then switch to the normal horn when he stops you.
-"I thought I heard a train come from your little car, nevermind you're free to go"
"OH WAIT!!! Tell me everything you know about Smarts!"
- I got blown at by a train horn today by someone in a Suburban.
I just drove even SLOWER

- I wish I got his plates...
