Know Your Limits Slalom: In a test of the drivers' awareness of their own abilities and limitations, each is asked to drive a slalom with the foam figures spaced 35m apart. They will then be asked to take a second run, with the gaps between the figures narrowed to a distance of their choosing. Ashley is up first, and in a far cry from her disastrous performance in the initial assessment, passes the first slalom with ease. This causes her to become over-confident, however, and she asks for an 8m reduction in the distance, which causes her to lose control of the car, hit the last foam person and nearly spin out of the track. Adam also manages his initial run with no trouble, but then makes a surprise request; instead of insisting on a single, large reduction, he asks for a series of additional runs with a further 2m reduction each time. Consequently, he manages runs with 2m and 4m reductions just fine, but 6m proves a bridge too far, and Adam subsequently admits that he should have stopped at his 4m run. Melanie handles her initial run reasonably well, albeit she becomes stressed out; despite this, she insists on the biggest reduction yet, at 10m. This results in her second run rapidly turning into a total disaster, as she spins off the track altogether, and her attitude leaves Andrew and the experts increasingly convinced that Melanie is the worst driver of the group.
Prior to Shayne's run, he's taken to a medical clinic and given an MRI scan, where it turns out that, contrary to Andrew's earlier fears that he might have sustained a brain injury in his childhood accident, Shayne is just fine from a physical standpoint. Despite this, he ends up becoming the only driver to fail his initial run, hitting the second-last foam person, after which he admits becoming target-fixated on and steering towards it. As a result, he instead asks for the distance between the figures to be extended by 5m, which he passes just fine.
The Cross: For this year's version of this challenge, each driver is placed at the wheel of a school bus, and asked to turn the bus around 360 degrees in a large cross made up of concrete blocks, with usage of mirrors and S-turns paramount to success. Ashley is up first, and despite initially doing well, she becomes increasingly careless and impatient, finishing the challenge with 12 hits. Adam, despite taking longer to get into the cross's first alcove than it took Andrew to complete his entire demonstration, soon gets the hang of the challenge, and finishes with only 2 hits. Shayne also does well, taking a little longer than Adam, but also getting through with just 2 hits.
Melanie isn't asked to take the challenge, and instead is sent on another public drive with Tim, which will include practicing parking up in parking lots. Despite this, she remains unfocused and uncommunicative throughout the drive.
Ashley also gets taken on a public drive, which for the most part she manages better than Melanie did, but she proves very nervous while driving on the highway, and admits that she still couldn't do it without Tim being in the car.
Camaro Challenge: The Icy Corner: In what is considered one of the show's most crucial challenges, each driver is given a lesson from Philippe in how to steer the car through a skid, followed by five attempts to navigate the Camaro around a simulated icy corner. Melanie speeds and locks up the brakes on her first three runs, then continues to speed and over-steers on her final two attempts, failing. For Adam, success in this challenge is paramount, as the accident that robbed him of his confidence was caused by icy conditions.
Adam fails his first run by braking far too early, then his second by over-steering, which causes him to completely lose his confidence. Despite this, a pep-talk by Andrew and Pat gets him back into the game, and he passes on his third attempt. Shayne does even better, and passes on his first attempt, putting himself in pole position to graduate this week. Ashley takes her runs with Shyamala as a passenger, due to concerns by Andrew that Ashley is taking Shyamala's advice to "embrace failure" a little too literally, and not making enough of an effort in the challenges. She subsequently fails her first run by speeding and pumping the brakes, and her next three by over-steering; Andrew takes over as passenger for her last run, but once again she speeds, causing her to fail.
When meeting with the experts, Melanie is sharply criticised by Tim for her repeated failure to apply the lessons he's repeatedly being trying to teach her in his public drive, and she admits that she's destined for the finale, as does Ashley. Both Adam and Shayne do want to graduate, however, leading to both men being shortlisted.
Cam and Philippe both vote for Shayne to graduate, for performing as well as or better than Adam in all of the challenges this episode, while Andrew and Shayamala vote that it should be Adam, citing Shayne's failure in the initial part of the Know Your Limits challenge, thus leaving Tim with the deciding vote. For the fourth week in a row, Adam misses out on the grounds that one of the other drivers was just that bit better, making Shayne the season's penultimate graduate.
