I think we have to accept now that 'The Knowledge' is now completely pointless. The uber driver has Waze, and that is probably at least as good 99% of the time

I think we have to accept now that 'The Knowledge' is now completely pointless. The uber driver has Waze, and that is probably at least as good 99% of the time and occasionally better since they'll know in advance about traffic accidents that close roads. Black cabs/drivers do not need to exist anymore in their current form.
