I'll bet in 5 years it's nothing more than a niche premium service - a high but lower priced black car service - though "traditional" taxis will have copied some of their easy to copy approaches to things. Taxi regulation isn't always ideal for customers, but as I gave up trying to tell people years ago (I WAS PROVED FUCKING RIGHT, probably), there's a good reason to have a legal monopoly-like (supply restrictions with regulation) system. Without it, the business won't be profitable.
