In the " Street Response challenge" crazy races test the limits of Dunlop Tyres. Racing in reverse down the looping car-parl levels looks quite spectacular.

But when you're an old cynical ad(wo)man like myself, you'll just note the tinted windows that hide the reverse-build inside the car, and yawn slightly as it's not as much fun when you know they're racing the right way around in backward built cars.

Still, racing is fun.
