Left foot parking brake, you only use when getting in the car and leaving the car. Start car, put in drive or reverse release foot parking brake (no lever on dash on CT). The brake moves up and out of the way of your left foot, left foot then rests on foot rest for the rest of your trip (nothing else to do). CVT gear box does creep just like an auto (which it is). When finally getting out of the car, stop and press park button on dash, press down the left foot parking brake, switch off car. Use it once or twice and it becomes second nature. At all other times when driving just use the main brake pedal in the middle (with the right foot). Motoring reviews are it seems written by people who have never driven the CT or do not understand how the CT drives.
Enjoy the car, learn how to get the best out of the engine set up, once you understand how it works it is an amazing drive. I am now on 12K miles and seeing 60 mpg for normal town driving. Really pleased I chose to test drive one and ignore the reviews in the press.
