Re: drinking, smoking and some basic biology.
"Smoking is *awful*. Not just for you but for me too. There is nothing good about breathing toxic compounds."
You have been conned. It's pollution. Nasty diesel. Idiot council traffic calming measures. My car does 40+ mpg on a run. It used to do 30mpg round town. Now it does under 20mpg. Even in the middle of the night the traffic light sensors are programmed to make lights go red as you approach.
Traffic calming measures are making your child asthmatic.
