Now if they could make it for 1 Avios per minute you have to wait for an Uber then it could be interesting ( or compensation in Avios when the driver cancels on you )

I understand the economics of it isn't attractive for a lot of the drivers and this is the root of a lot of the issues .. but as a user it's really become so much worse in London than it used to be - will do most things to avoid Uber these days , hard to rely on it ( and even if you can get a car the prices have become rather 'adventurous' quite a lot of the time )
