gramps champ 

The overly slow and cautious driver, usually elderly but not necessarily, who manages to stay in front of you in traffic. They turn where you want to turn, exit where you want to exit, and go into the same parking lot you're heading for, and so they are always in the lead. You have trouble passing them because there's only one lane or else traffic volume is just too busy. So much to your frustration, you remain in second place while they undeservingly take the checkered flag!

Jack: "How come you're so late? The movie's about to start!"

Danny: "I was rushing, but I got stuck behind two or three gramps champs on the way here! It was so annoying!"
