I wish I had one of these this morning. On my commute there is a clover leaf interstate exchange that completely gridlocks right as I enter it. I always want to just stay to the outside and zip past all the cars, but I never do. This morning as I come to a complete stop the SUV behind me pulls right up next to me. I turn my head to the right and I'm looking directly at the driver side mirror. This pisses me off mostly because it is illegal for me to split lanes. Drivers get pissed off if I split or filter. So if I can't share the lane with you, you can't share the lane with me! I gave her the stink eye, but she wouldn't even turn her head and look at me. It would have been great to toss this yellow card on her hood.
