I use my bike almost every day to commute. Even during 5 of our '8 winter months' (December, January, and February are tricky due to the snow). When I don't, I walk or take the streetcar. All my life (except 2 horrid years I lived in Mississauga) I've lived within walking distance from a grocery store or supermarket, so I walk to get groceries and such (in winter or not).
Some evidence for the 'bullshit' you call:

Some of the most polluted places in our cities are in front of schools, in large part because of the idling cars of parents dropping off their kids. Children are more vulnerable to air pollution than adults because they breathe faster and inhale more air for each kilogram of body weight. Being inside a car is no protection from air pollution either. The International Center for Technology Assessment reports that exposure to most auto pollutants is higher inside vehicles than at the side of the road.
As a kid I loved to be dropped at school by my father, and school was conveniently located on his way to work. It took him less than 15 minutes to get to work, and my school was down a very steep hill but only a 6 minute drive away. I understand why you would prefer doing it, but I believe we must live within our means.
If you use 100x the amount of energy that the average Canadian household uses that's entirely up to you. If you want to drive a F1 car again, up to you. I don't really care. I just don't think the infrastructure to sustain such lifestyles should be subsidised by the government, that's all.
If you are causing deaths by sitting on an idling vehicle in crowded intersections that's fine, but healthcare costs will increase as a result for pedestrians AND drivers, and you shouldn't be offended to foot some of the bill. I use 100x more electricity than someone living in a Venezuelan slum, but I'm willing to pay over the odds to get that electricity from sources we can more or less sustainably harvest, as opposed to carelessly using up resources we simply shouldn't be building our long-term future on.
To make a long story short: you should be entitled to buy whatever you can afford, but you should pay its real price. Not saying you specifically don't, btw. But most suburban communities in North America (think Mississauga, Etobicoke, Scarborough) are kept financially afloat artificially through huge government tax-breaks and subsidies.
