Google appears to already take care of the 'fast routes become slow routes due to popularity' issue. Frequently in London, Google Maps will pop up a "Faster Route Detected" alert and will divert onto a quicker path.

Google Maps would also change my London commute route on a daily basis given the changes in traffic patterns.
