At the very least, if the only penalty is getting booted off the 'platform', getting added to Uber's platform is relatively cheap. Getting added to the black cab 'platform' requires getting licensed, which takes years and costs a lot of money.
I'd imagine that fraudulently impersonating a black cabbie comes with significantly more penalty than getting 'booted off the platform' (license revocation).
Not that America is any better these days, NJ recently decided to get into the game and started to go after Uber.
A black cab driver has made a more significant investment in that license and will be much less likely to jeopardise it than some shmuck loaning out his uberx login -- especially when Uber not only doesn't do anything to stop it, but encourages it with more dark patterns.
There is concern that this is happened in the past and penalties are extremely severe: the owner of the original license will lose their badge and may face criminal charges.
It's a bit hard to describe the taxi market in London to anybody who doesn't live here, but it's a closed shop only to the extent that if you're prepared to do the work to get a badge, it won't cost you $1m like New York, but you will have to put some hours in, and you'll get known by many other black cab drivers.
If you show up with "Dave's cab" and you're not Dave, you're going to get asked questions. Do it a couple of times, and they might decide to pull your badge number up.
A few years ago a genuinely licensed black cab driver was convicted of rape and sexual assault, and as a result the community was shaken: it was the first time in over 300 years where a licensed operator had been convicted of such a crime, and they now look on newcomers with even more suspicion.
There are no lobbyists in parliament, and most black cab drivers I know have modest incomes. They declare an average of £38k/year, but as a cash business (until recently), it was assumed they were actually doing about £50k/year. Good money, but not megabucks.
The system is supported because it's worked for hundreds of years. Their chief complaint against Uber is whether their drivers have to undergo the same amount of vetting as they had to (they don't), and whether the fare structure is fair (it isn't, especially as it's VC-subsidised).
Uber is a great solution in many places that have poor transit and poor taxi solutions already. London isn't one of those places, and hasn't been for hundreds of years.
This boogeyman trope needs to die. Uber is not funded by VCs anymore.
I guess demeanor, dress, etiquette, and a bunch of other pleasantries are still a commodity, but then again the stereotypical NY cabbie gets their fair share of likes and dislikes from the movies and tourists too. To me, Uber and Lyft are indispensable for doing business across teh US now. I can go away with car rentals where I only need to make a few hops during a day, and I can stay somewhere without worrying about parking or hailing down a cab.
