Water Tank Challenge: The drivers are taught gentle braking in this challenge, where water is placed in a tank over a car. The objective of the challenge is to maneuver the car around an obstacle course (complete with several surprises), with jerky braking causing the water to overflow from the tank, soaking the occupants in the car.
Fastest Performer: Bob performed the fastest at 5 minutes and one second.
Slowest Performer: Madalena went through 12 minutes and 20 seconds.
After performing admirably well in a parallel parking challenge, despite doing lousy in the water tank challenge, and in a challenge during night-time, Bob shows that he can be patient, and graduates. He also received the highest score in street sign identification with a perfect 5/5, while Heather scores the worst with only one sign correct.
