The smoking cessation classes I participated in taught that the physical act is as much of a habit as the the addiction. You are in the habit of lighting up in order to have a brief respite from whatever you are doing, or that you just are in the physical habit of having one under certain circumstances, such as getting into your car. You have to break these habits as well as the addiction in order to be successful. I quit over 20 years ago now, but even now still have the occasional dream of falling off the wagon and waking up thinking that I really f--ed it up all yesterday, only to realize it was only a dream! Good on you that the taste is no longer that appealing, you are on the road to finally quitting for good. Now just ignore that little red fellow on your shoulder every time you drive, or have a cuppa joe, or take a break from the desk. It does get easier with time.
