I find the numbers below very very sad…
In 1969, 41 percent of children either walked or biked to school; by 2001, only 13 percent still did, according to data from the National Household Travel Survey.
In many low-income neighborhoods, children have no choice but to walk. During the same period, children either being driven or driving themselves to school rose to 55 percent from 20 percent.
Experts say the transition has not only contributed to the rise in pollution, traffic congestion and childhood obesity, but has also hampered children’s ability to navigate the world.
In a study of San Francisco Bay Area parents who drove children ages 10 to 14 to school, published this summer in the Journal of the American Planning Association, half would not allow them to walk without supervision, and 30 percent said fear of strangers governed their decision.

It’s okay. Your pathetic fat little children will fall behind in every metric that matters: career advancement, education, mating and health.
My child, raised to be independent, will reject your child as she chooses a mate, an employee, service provider.
(By ‘your’ I refer to the average paranoid parent reader with lazy fat stupid kids, not the author of this blog)
