A coworker asked me if the r53 had hill assist. I didn't know until now that this even existed and after asking a lot of questions, I'm even more confused WHY it exists. If you don't know, the hill assist feature apparently engages the brake or clutch to keep your car from rolling backwards when moving from a full stop on an incline. I thought you used the brake pedal for that? Anyway, what do you think? Does the r53 need it? Do other models have it? Is it just another thing that will break and complicate things and add another chapter in the service manual?
