The traction control programming seems to be the best I've ever encountered. In normal spirited road driving on snow it has not once cut power totally and left me standing still like other cars do. It is very annoying and could even be dangerous. My CLA does this very easily, as soon as it detects front tire slip it cuts all power and then I'm in the middle of an intersection standing still for what feels like forever. So, another positive for the GR-Y. Also the car didn't care about light overlap of thottle and brake and allowed light taps with left foot to control the cars trajectory. Not sure how much it allows it but at least enough to be usefull in slippery conditions.
