> I am asking sincerely. Certainly "the knowledge" doesn't include local traffic conditions a la Waze. Experience provides that, I guess. Waze is perhaps better in US grid style systems with lots of large, laid out roads but In London the streets are tiny and the traffic patterns very different. I think the traffic follows in a predictable ebb and flow pattern based on the week day and time, which you can pick up easily enough if you spend all day in it. I've seen the Google maps traffic display in London and it's not terribly useful: all red everywhere at peak times, yellow/green off-peak. It's anecdotal, but in London every taxi experience has been superior from a directions point of view. Uber sometimes gives drivers crazy directions that make no sense and the drivers just go along with it. That being said, Uber is a fair bit cheaper so it's all a trade off I guess. Fankly, if I've got money I don't mind spending it on a black cab, I see it similar to supporting local businesses over buying off Amazon - a good idea for smaller purchases, but the discounts on larger items are often too good to turn down.
