The point isn't that one gets into an exotic car and sees something different. I've been in a few card with strange controls for the handbrake, but they are obviously different with pull shafts or foot pedals and releases. This is a case where they made the operation completely different, while looking like a standard control. So someone gets in, looks around, thinks "yep this all looks familiar I can go now" and only finds out later that it is different. Even if they do know, the muscle memory associated with decades of having it work a certain way mean that unless you are paying close attention, it's easy to forget and do the old movement.
E.g., in my Dad's Volvo, I often start the wipers when going for the indicator. It's annoying, but after a few minutes of driving, my brain has adjusted and I'm OK with it. But I make that mistake a few times every time I drive that car, which is only a few times a year. Luckily, that mistake isn't something that can result in a dangerous situation. The worst is that turning on the indicator signal is delayed by a second or two, and I get laughed at by my Dad.
Key operational controls should either work the same, or look and feel completely different to ensure that users' muscle memory doesn't result in inadvertent operation.
