Uber loses licence to operate in London, will still operate while appealing

It seems that 43 out of 45000 drivers were able to drive illegally - it's bad, but not a horrific. Is there a time line available? Was this is in one year or overall since Uber's existance?

43 unlicensed drivers managed to put 14,000 passengers at risk.

London is not an easy place to drive, and many of those passengers would have been vulnerable: lone females, people who had too much to drink, etc.

You might not consider it horrific, but by London standards it is completely unacceptable.

How would this compare to the old school taxi industry? Are there any numbers available that London publishes for comparison?
