From The Register:
Transport for London (TfL) has said that it doesn’t think that the app used by Uber drivers is in breach of the law by allowing them to use GPS and navigation to calculate charges, but it wants to refer the issue to the UK High Court.
The capital’s transport authority said it didn’t agree that smartphones used by private hire drivers could be classed as “taximeters”, which are illegal in private cars.
However, it said that it would be asking the courts to get involved “given the level of concern among the trade” and the fact that the law was “unclear” on the issue.
I can't track down a law that makes it illegal for anybody other than 'official' taxi drivers to use a taximeter, but let's assume that such a law exists.
Which Parliament in its right mind passed such a law?
AFAIC, cab drivers can charge by the mile, by the minute, agree a price beforehand, what on earth business is that of anybody else other than the drivers and their passengers?
