I'd argue that if you're only 10 minutes away from work by car, then you're not really living the "big wasteful" suburban life. Real sprawl (I'm unfortunately quite familiar with the kind outside of Toronto) involves long drives and frequent wrestling with slow traffic to get anywhere, especially during rush hour. Suburban houses are cheaper precisely because they're far from places people want to be.

That said, with Skype, remote work, Netflix, and Amazon Prime, I guess who really needs to go anywhere these days anyhow?
