In general, Entrapment as a defence only works if the defendant would not have otherwise broken the law, without the influence of the entrapping officer. i.e. they were an otherwise upstanding citizen, and only broke the law on that specific occasion, and only because somehow the officer managed to persuade/pressure them in to doing so. (Still depends on what you did though).
In this case, Uber drivers are willingly driving illegally, without the required license, and likely without valid insurance, therefore are already a danger to themselves, their passengers, and other road users. So it's not entrapment, as the officers are not the ones making them break the law, the drivers are doing that themselves already.
