Brandon and Karlene were in tears after finishing this challenge.

This is the only challenge that looks hard for me. I'm not sure I'd be able to do it under pressure without practice. After all it's not very common to pass through several narrow spots at high speed and also need high steering adjustments in between. But I'm guessing I could be misjudging the challenge as the drivers are terrible in pretty easy setups that also require geometric awareness of the car.

That fail
