I'm not sure how I feel about this. On the one hand, some of these regulations are clear attempts to just protect the taxi industry from new models. On the other hand, some of the regulations (like having some basic insurance to cover if things go wrong) are pretty reasonable. On the gripping hand, both Uber and Lyft are both just blatantly ignoring regulations in many jurisdictions, and whether or not one thinks the laws should be there, it is hard to think that having cheaper car services is such a compellingly necessary service that it can morally or ethically justify ignoring laws.
If you wish to speak of morals and ethics, perhaps you should review the existing structure and their pricing model first.
There's a reason we have a compelling argument for competition here, and it's not because they have cooler looking cars.
There certainly is a compelling argument for competition, as there is for proper regulation. So when one looks at the existing structure the question becomes what parts of it need to be applicable to new entrants providing the same service, i.e a ride for hire? Uber et. al. are merely a modification of the existing call a taxi on a phone model and thus should be subject to similar regulatory oversight. You contact a dispatcher, they send an independent contractor to pick you up and take you to a location for a fee. They may not have a medallion on their car and may or may not own the car but the end result is the same - a ride to a location in exchange for money.
Of course the existing companies are fighting tooth and nail becasue there is a lot of money at stake. In locations where medallions are scarce people can have hundred of thousands of dollars tied up in medallions, the medallion may be the most valuable thing the company or individual owns. Uber threatens that by putting cars on the road, thus threatening to overcome the artificially constrained supply of cabs and make owning a medallion necessary and thus lowering the value of existing medallions. So one can expect the medallion owners, as well as those who lend money to people to buy them, to fight back. Interestingly enough a medallion is one expensive item that is tailored to people with poor or no credit, since as one lender put it "If they don't pay all I have to do is pry the medallion off of the hood. I can then resell it but they can no longer drive so they'll do anything needed to make their payments."
