By better quality and lower prices? The taxi industry has needed a shake up for a long time. I won't ever use a black cab again in London and suspect uber will do very well in Brighton too, or will cause Brighton cabs to up their game, which would be a good result too!
What do you mean by it needs a shake up? Maybe it does but this doesn't mean allowing the profession a race to the bottom.....like so many other sectors have now experienced. Brighton and London taxis are not perfect, see my earlier post about my own experience and the Tuk Tuk thing was crap, but imho their livelihoods are worth protecting and that means not being severely undercut by uber.
I think professions are worth keeping...I'll stick with proper taxis.
