Smokers take note: starting on October 1, 2015, you may no longer smoke in your own car (or anyone else's) if you're sharing the car with a child under 18. The ban covers England and Wales (and the Scottish parliament is considering a similar ban).
This is a Good Thing, especially for the chidren we love. Why expose them to the risks of second-hand smoke? The anger unleashed by the Volkswagen diesel scandal shows clearly that we value the health of our lungs, and there's no worse attach on a child's developing lungs than having them share a small confined space with a cigarette smoker.
Most children already associate the cigarette lighter with the power source for their iPods and whatnot, rather than with lighting up an actual cigarette, anyway.
In the United States, laws on in-car smoking in the presence of children vary from state to state (and sometimes between counties), and the age of the child varies likewise, from 8 in Vermont to 18 in California and Oregon.
If a universal ban of smoking in cars were to be installed, perhaps we can leave out the fire retardants in the upholstery, that come with their own health risks.
And that would be a Doubly Good Thing.
