There's a labour market for that.
> lack of labour rights,
That's for the government to deal with.
> surge pricing,
Surge pricing is awesome: at least you can still get a cab if you are willing to pay. As opposed to no cab at any price.
> lack of disabled accommodations,
Yeah, that's annoying for those in need. I propose giving disabled people more money, so they can then vote with their newly enlarged wallets. (And perhaps there's something more efficient for them than enticing taxi drivers.)
> no guarantee of service in all areas,
Why should city dwellers subsidise those yokels?
> lack of fare caps,
As long as the fare structure is known before I get into the cab, no problem.
> no concessionary travel,
Just give poor people more money. No need for concessions. (I've never seen any regulated taxi with concession fares. Only in public transport.)
> having to use a smartphone to pay,
> unaccredited and unknowledgeable drivers,
Not less knowledgeable than most `normal' cabbies, as far as I can tell. But, depends on the area. Eg London has some pretty knowledgeable cabbies.
> generic unmarked vehicles, etc.?
Who cares? You can pay more for an UberBlack, if you want to have a non-generic car.
