> "Surge pricing" is no more a scam than any other market-based pricing mechanism.
Surge pricing on an unknown fare (metered) is actually quite ridiculous.
For contrast, when I order a Lyft line in Manhattan, it gives me an exact price quote (not an estimate, but the exact quote) before I order the ride, taking all surges into account. This means I have perfect knowledge of what the price is going to be before I decide whether to take the ride[0].
Uber has consistently refused to implement price quotes, to the point where they have literally jeopardized their existence in at least one city because of it: all of the legal problems they have in London would be avoided if they provided price quotes in advance.
Uber has been really clever to frame the controversy as a debate about whether the cabbies should have to take an exam. But the fact that medallion cabs in London have to take the street exam is all moot, because if Uber provided price quotes in advance, they would be classified as a different kind of car service which doesn't have to take the street exam in the first place.
Instead, Uber would rather launch a coordinated PR and legal campaign against the entire medallion cab system in London, just to avoid implementing an incredibly user-friendly feature.
[0] This feature may not be in all locations yet (in fact, I don't know if it even works if the destination is in another borough), but it's clear to me that this is at least where Lyft is headed, whereas it's clear that Uber is committed to not providing price quotes.
