The indicator controls are a good example of this. They used to mechanically click into one of 3 positions, indicate left, off and indicate right. This made it very easy to switch them off. Now when you want to manually switch off the indicator it's very easy to to go too far and start indicating in the opposite direction. The only way to know what position they're in is then to look down at the lights on the dashboard. It's seems a huge step backwards in usability.
