Difficult to work out what Uber will do. They've withdrawn from UK locations before, and I'd guess that if there's no significant change in the offing as regards the knowledge or whatever, then maybe they'll pull out of Aberdeen in the new year. Can't really see that throwing a whole load more money at it all will make much difference.
Ditto Dundee - not sure if they ever announced a start date there, but I'm sure the timetable was broadly similar to Aberdeen - late summer/early autumn launch.
But not sure they've even had a soft/limited launch there, never mind a full-blown one
Of course, that's assuming their thinking is a hard-nosed, business-based, profit-oriented approach, as opposed to maybe just not wanting to lose face and/or trying to get one over the likes of their opponents in the Aberdeen trade, and politicians etc.
Recall that in fact Uber was set up because founder Travis Kalanick wanted to get back at the medallion taxi cartels in the States, and because of bad experiences he'd had with drivers in the like of Paris (both of which make even the worst of our own plate cartels look like small beer).
So if it's less about a business proposition and more about settling scores then, as Sussex says, the Aberdeen trade shouldn't get complacent
(Kind of reminds me of 203020 in Dundee, a private hire operation set up by the wealthy Marr brothers, who wanted to change the face of the trade - so they bought dozens of E-class Mercs, actually employed drivers and paid them a wage, and they had fancy uniforms etc - all at the council's taxi tariff
[And, as anyone who knows the markets in both Aberdeen and Dundee will know, at least back then 20 years ago Dundee's trade was like a scrapyard compared to Aberdeen's, thus brand new E-class Mercs were a lot more transformatory down here than they would have been up there...)
However, the wheels gradually came off (almost literally), and after a few years it all eventually morphed into little different from the existing trade, and laterally became part of one of the long-standing offices, as I recall it.
Of course, Uber is a different beast, and wants to transform the industry in a different way, and to an extent actually has, but not absolutely everywhere.)
(A parallel from a different industry might be GB News
Which aimed to transform news and current affairs broadcasting from a political perspective. But which is losing money hand over fist. So if it was purely about profit and loss then it would probably have closed by now. But it's about more than that, and its backers have very deep pockets
