As with previous years, eight people, nominated by their family or friends, enter the Driver Rehabilitation Centre to improve their driving skills.
Robert is reminded that driving too slowly is an offense (he admits actually being fined for doing so at least once) and the experts quickly identify the need to address his high-speed nervousness.
Cam and Shyamala both vote that Robert should graduate, as they feel that his major issue of being too slow and lacking in confidence has been addressed and are unconvinced that Klyne's attitude has sufficiently improved.
Furthermore, Dallas overcame her stress-related problems, while Andrew argues that the panel should not overlook Diane's failure in the Eye of the Needle challenge at reduced speed.
Prior to the experts' deliberations, Cam informs Margherita that wearing wedges or any other form of cumbersome footwear is considered a criminal offense if it is judged to have been responsible for an automotive accident.
However, the experts also discuss the possibility of forcing Margherita to pick a new nominator and kicking Cheryl out of rehab for her disrespectful behavior after the previous challenge, in what would have been a first for the series.
Andrew and Cam are adamant that, despite her lack of enthusiasm, Diane is a much better driver overall and that Margherita is not ready to graduate, but are unable to convince the others to change their minds, leading to Margherita being the penultimate graduate, once again ensuring that there will not be three women in the finale and sending Diane into the finale with Kevin and Flora, much to the dismay of Andrew, who tells Margherita to her face that he totally disagrees with Tim's, Shyamala's and Phillipe's decision and that Diane should be the one leaving rehab instead of her, yet nonetheless congratulates her on having improved so much, as she had been one of the worst drivers in rehab during the first few episodes (and especially the worst during the Three-Point Turn).
Andrew is left with the deciding vote, but notes on the difficulty of actually deciding who is worse—both passed just two challenges over the course of the whole season, both have nominators who tend to exacerbate their problems (Lenny by not pushing Kevin harder and Frank by constantly interfering with Flora's driving and giving her bad advice), Flora did worse on the Slalom challenge and Kevin worse on the Mega-Challenge and both were equally bad (in slightly different ways, as Phillipe stated) on the final Road Test.
As the two are driven away by Lenny and Frank, respectively, Andrew ends the season on a somber note by voicing his concern that two drivers could be so equally and so terrifyingly bad.
