I know of those. Uber denies it but why even show cars if it is 'fake'. They are either there or they are not. If they are there to be 'ghost cars' then they are there to intentionally deceive.

And I was more talking about a change in the route. Which definitely happened in my case. The route was changed with NO need as the route was clear(direct route). I was charged 20% more for no reason.
