There is probably not going to be Uber in London - unless the courts overturn the mayor of London's ruling. Personally, that is a huge annoyance - I've come to depend on it absolutely. I can't imagine how the 45,000 people who could be out of work must feel.

This decision by London will be a boost not only to all traditional cab and tuk-tuk drivers worldwide who can point to a precedent, but also more generally for disrupted industries everywhere, who will use this as a cause celebre of how unions can win against the tide of digital transformation that consumers love, but which threatens their way of life.

I think this is a setback to progress, but one which will - in the end, be good for consumers.

If you look at the reasons given by TfL, almost all of them are addressable by the ride-hailing giant; and that's got to be the lesson that these giant megaliths take on board. Better driver training, background checks on drivers, more honest reporting of incidents when they happen - none of it is insurmountable - and all of it would improve the safety and performance of the service.

Take a leaf out of Facebook's playbook - once it became clear their system allowed people manipulate voter opinion in the US election, they have dedicated a tonne of senior time to solving the problem.

To me this is an ethical cultural issue that's starting to become more prevalent in the world and which hails from silicon valley; it starts from the relentless drive for 'weekly growth' beloved of VCs - which is the 'destructive gale' that blows through corporate culture. Everything is sacrificed on this altar.

Tristan Harris who is brilliant on the ethics of silicon valley shows that ethics is more than just company culture, but is a crucial and under-developed aspect of everything from the products we develop, to the behaviours our technology drives. 

Ultimately I hope this is a wake-up call to Uber, I hope they address the problems and come back to London soon with a revised and improved business. Otherwise, I'm going to have to unleash my wolf-whistle to hail black cabs on the streets of London again - and nobody wants to hear that.
