Prompt: What did Cisco learn won't fit in a car?

Cisco glared at the small piece of the drone sticking out of the back of the truck. He attempted to close the car doors again. He pushed as hard as he could. He saw at most half an inch left and felt the drones start to shift inside, but his shoe gave way before the door managed to click.

Caitlin gave a sympathetic shrug. "As much as I'm skeptical about the canyon jump, it might be easier to get Barry to reconsider."

Cisco paused as if to consider it before looking back at Caitlin. "You do realize this is Barry we're talking about. Barry, who has a stubborn streak a mile wide. Barry, who will do anything to get faster if it will save someone. Because, that ain't gonna happen, and I don't want to see him splat against the mountain side."

Caitlin opened her mouth to retort, but as Barry's doctor, she knew how hard it was to keep him out of trouble. Instead they were his safety net, so when he got into trouble he wouldn't fall to far. Caitlin walked forward and opened the car doors wider. "Perhaps, there's something we could move around or put on our lap."
