The deal-breaker for me with the upcoming MK2 is going to be how intrusive the driver assists are. It's surprisingly easy for these features to ruin a good car.
The thing that's bugged me the most about the MK1 since day one is how you can't permanently turn off most of the assists, unless you go for some questionable dongle from eBay. It's incredibly frustrating. If the MK2 comes with even more of these assists that can't be disabled or are tougher to turn off, then I'll be more than happy to stick with what I have. Unlike the new M2 and Civic Type R, where you can easily disable these features and don't have to push a bunch of buttons every time you start the car.
I understand that these assists are required by regulations and can be useful for some, but personally, I'd love to be able to disable all of them. I hate them with a passion. To me, a true "driver's car" shouldn't have any computer interference, no matter how minimal.
