Does it? A machine can indeed do a better job (in the sense of requiring negligible training) of knowing all the streets and democratized “the knowledge” which previously was the purview of a small guild.

I am sorry for their sunk cost, but really minicabs+gps and now uber/Lyft et al are as good, or would be if taxis didn’t have a pick up monopoly.

From previous articles on "the knowledge" I believe that no, a machine cannot really do "better" or not yet, at least.

IIRC at the exam you could get questions like "The passenger tells you that his cousin mentioned a building with a bas-relief of Holy Mary holding Jesus, it was right around the angle from his hotel, but he does not remember the hotel's name".

You are supposed to know the place and the best way to get there, based on just this (also, a good number of "knowledgeable" taxi drivers go for an official London Tour Guide exam soon after, with relatively little effort, considering they have already memorized thousands of places, monuments and architectural details).

Untrained driver + Google Maps sits on a different point on the cost / benefit curve than Driver-with-the-Knowledge.

Different customers might prefer different total packages on different occasions.

I for one rarely need the more expensive Driver-with-the-Knowledge option, especially when I can ask Google many of the same questions.

[Pamar]

I may concede that it can perform “adequately at a lower price point” (I use Google myself when I am not in my hometown), but the parent wasn’t talking about price.

[eru]

I went off the phrase "A machine can indeed do a better job [..]" and was seeing the price as a big part of that package.

Looks we agree about everything that we actually made explicit. The disagreement was about the implicit meaning of whether price was included in the meaning of 'better job'.

The Knowledge has a very important secondary effect - it creates a huge sunk cost, vastly increasing the downside of losing your license. Getting a green badge takes three to four years of full-time study. You can lose it for relatively minor offences like short-changing a passenger or taking a tourist on the scenic route. Hackney cab drivers with a green badge have a far stronger incentive to do business honestly than a minicab or Uber driver.

A theoretical machine could do a better job. In practice, we can't build anything that can reason about routes anywhere near as well as London cabbies do. And I'd say that even without knowing about The Knowledge.

Pamar's comment above has a very good example of the kind of thing "a machine" is still very, very far from achieving.

It certainly CAN but a regular GPS just sucks compared to the Knowledge.

[carlmr]

With enough driving experience even with GPS you'll learn enough about some of the cases where you can know better.

[jacobush]

People can learn, of course. I'm just saying that a an ever changing score of Uber drivers will not be comparable to drivers with "the Knowledge". Any other claim feels preposterous to me.

This can of course be replicated with a computer, but a simple GPS is not going to cut it. Advanced machine learning, voice recognition like nothing I have ever seen, very good A.I. to resolve misunderstandings about where tourists and other non frequent travellers might really want to go instead of where they actually said. And so on and so on. We can get there. An underpaid, recently started and soon to be replaced, stressed uber driver in his uncles car armed with a GPS app is just not going to cut it. Yet.

Forcing people to pay for the gold-plated service of the Knowledge seems like a bit trade-off though.

[DanBC]

They're not forced to pay for it. They can use other private hire cabs if they don't want a taxi with a driver with the knowledge.

[eru]

Are they allowed to hail from the street?
