Taxi Driver and the Red Lights

There's this guy riding in the back of a taxi. He suddenly notices that his driver is not even slowing down for the upcoming red light, and together they speed straight through the busy intersection, on red.

"Hey, you just ran a red light!" the passenger shouts nervously.
"Relax, man, my brother does it all the time," is the cabby's laid back response.

A minute later, the driver does the same thing again, right through another major intersection. "You did it again!!" the passenger cries in fear. "Man, would ya' quit worrying? I'm telling you, my brother does it all the time."

A block further on, the same story. Another major intersection passes like a blur as the cab goes speeding through the red light. The passenger is growing frantic by now. "You just ran three red lights in a row without even slowing down!!!" he whines, now white as a ghost. "Look man, would you just relax? I'm telling you, it's cool. My brother does it all the time."

But just as these words are leaving his lips, the cabby begins slowing to a stop. By now the passenger is truly confused, since the light just ahead is bright green. "The light's green, so why on earth are we stopping now?" moans the passenger, exasperated. "Oh, this is the part of town where my brother lives." replies the cabby.
