US Top Gear Promo - Ride in a Supercar Taxi

I happened to stumble upon this promo running in Midtown for the new US version of Top Gear which starts next week. They had 6 different supercars done up like cabs taking people for short rides around a few city blocks. I waited about 15 minutes for my turn in my dream car... the Mercedes SLR McLaren. 0-60 in just 3.2 seconds, the fastest out of all 6 cars on offer... however, even though this was a Top Gear promo, we didn't get out of first gear!
