The physicist in me won't think it's cool until there's some monte carlo simulations of commute times with some additional random walk information for alternate routes and stop light entropy, then a log-likelihood fit to find the best fit commute time. Just kidding, it's alright, it's kind of off for the SF/PA commute though, by nearly a factor of two for many places in SF, unless you're doing absolute worst case scenario every day of the week.
