Stupidity: When Spider-Man confronts Aleksei Sytsevich in the truck while he's plowing through the busy streets of New York, he sits there and starts cracking jokes instead of immediately trying to stop the truck, effectively allowing Sytsevich to potentially injure or kill numerous people in the process. He even allows Sytsevich to fire a gun out of his window and into the open crowd instead of trying to disarm him as soon as he sees the gun. He nearly misses school graduation ceremony because of this.
