some smart car tried to get in between me and a bus to get into the other lane, which wasn't moving of course

so I am stuck behind this smart car who thought 'oh I'm so small I can go between these cars like a privileged asshole"

still angry

That's when you run them the fuck over and say "oh, sorry, I didn't see you there, you car is just so SMALL!"

Also, one of the many benefits of having a shitty car is that no one will ever pull out in front of you.
