Monopoly? Well I did always like to be the racecar...
It does sound like they'll pretty much have a monopoly over London's "car club scene" with 1000+ cars. But I can only see this as a positive thing, for an enterprise like this scale is only going to drive down costs, and as it stands the merger looks like it is already going to reduce prices for Streetcar users even if they will no longer solely be using sparkly new Volkswagens. Furthermore the availability of so many more cars in so many places and the increased likelihood of expansion into new markets (some in Newcastle and Durham would be appreciated!). Overall it seems like this will benefit consumers and while it may put its competitors at a disadvantage, I'm sorry that's business, second best is first loser.
Now where did I put my "Streetcard"...
