Sibling pressure

An Uber is cruising down a boulevard when it runs a red light. “Hey!” the passenger shouts. “Be careful!”

“Don’t worry,” says the driver. “My brother does it all the time.” He barrels through the next red light, and the passenger screams, “Stop doing that!”

“I’m telling you, my brother does this all the time.” They approach the next light. Just when it turns green, the driver slams on the brakes. The confused passenger asks, “You just ran two red lights. Why would you stop at a green?”

“I had to,” says the driver. “My brother might have been coming.”
