Been driving into the city for 22 years, not as a cabbie but a frustrated commuter. There is no knowledge that can predict a system as complicated as London, as you will see by the number of taxis wedged in all the traffic jams.

However, the all seeing eye of Google Maps for example which aggregates just about every bit of info there is is all powerful. "drive home" - 42 mins, 8 mins of traffic, pick a route, gets worse on the way home, "faster route found!"
