"$150 for a tow truck?! Nah, I'll just tie my car to this bus. What could go wrong?"
And I'm sure in his mind it seemed like such a genius idea. The key mistake here: forgetting the universal rule that bus drivers simply don't give a shit. I once saw a bus driver close the door on an old lady in a wheelchair who was on her way to volunteer at an orphanage for three-legged puppies, just because she was a nickel short on the fare.
For added effect with the video from Aurelijus Gruzauskas, I suggest playing this sad trombone right at the 0.44 mark.
