The Balance-Beam for Unbalanced Drivers: In one of the most heavily-hyped challenges of the season, two cars, controlled by a contestant and their nominator, must try to balance the cars out on a teeter-totter rig. The cars are miked up to each other to facilitate communication, and a complex rail and chain system prevents the cars from hitting each other or go off the teeter-totter. Ed and Elizabeth, in a surprising show of patience, manage to balance out the fastest. Shelby and Billie-Jean also manage to balance out after a lot of work (humorously, Andrew was seated in Billie-Jean's car, and was forced out in order to get the cars to balance out), as does Jennifer after watching Jon adjust and laughing in the meantime for half her run. Neither Jason nor Marnie finish the challenge – both pairs had given up after an hour.
Parking Cross: In a simple challenge, a car is situated within a small cross, and the challenge is to park in the four arms of the cross, which can be done in at least 29 turns. Marnie is surprisingly the fastest at the run, and Billie-Jean puts up another strong performance. Ed once again lets his aggression gets the best of him, while Jennifer nearly breaks down. Jason's biggest challenge is not to let Adrian get the best of him, while Shelby's run is none too spectacular.
Driving on Ice: To simulate the icy conditions of winter within the summer driving season, a hydraulic skid car is employed. The hydraulic car is set to raise one end of the car via remote control. After being given skid car instructions by a veteran ice driving instructor, the contestants take on a simple challenge in the skid car: they must simply go downhill in the skid car in what is more or less a straightaway in park in front of a wall, being fully aware that the skid car may activate during the trip (the twist is, of course, that it will not activate at any point during the run). Marnie (who took the longest to learn in the lesson), confident in her belief that any skid on ice will result in a car crash, is completely surprised at the result – a perfect run, showing her that she needn't drive in fear of an ice skid. The single run shoots her confidence through the roof. As for Jason (the only other driver whose run is shown), he believes that he would skid into the wall, and thus accelerates into the wall to regain control. This destroys the skid car.
Riding a Bike: Head instructor Scott Marshall has always compared driving to riding a bike. The fact that Shelby has had no experience in riding a bike leads Andrew to teach him. Although he struggles to ride even with the training wheels on, after two hours, Shelby has achieved one of his lifelong dreams.
Stick-Shift Driving: In this simple driving challenge, after being given a lesson on stick-shift driving by Scott, the contestants must take a standard transmission car and drive it up a straightaway (peppered with stops), perform a three-point turn, and back down the same straightaway. Three of the remaining contestants have experience in driving stick-shift, and for Marnie, it shows as she scores a near perfect run (hitting obstacles only at the very last part of the return leg due to poor cornering). Ed and Billie-Jean are the other two, although Ed quickly gets into anger-trouble (elbowing Elizabeth at the turn) while Billie-Jean stalls her car as she makes the turn, starting off a dangerous chain reaction in her behaviour. Jason's husband Adrian also has experience in stick-shift, but it does not pass onto Jason as he hits obstacles and stalls the car repeatedly in his run, nearly breaking down on the return leg. Jennifer breaks down and needs a smoke break at the turn, while Shelby burns out his clutch in his car, forcing him to redo the challenge in a backup car (which was also used by four other contestants). He stalls the car 38 times in the new car, and nearly burns out the clutch there as well.
Again, the judges are split at the end of the episode. Cam and Andrew are both confident that Billie-Jean, passed over twice already, has shown repeatedly what it takes to graduate. However, Phillippe and Dr. Gembora prefer Marnie's dramatic improvement. Scott would rather graduate both, but is pressured into choosing one. Billie-Jean is passed over for the third straight episode as Marnie gets her license back.
