Strange that if it isn't a solution for taxis that they should dedicate a whole section of their website to just that
That claim is utter nonsense and shows a complete lack of understanding of the issues in the industry as is this whopper...
Efficiency savings do not come from accurate destinations. Efficiency savings are made with complex dispatch algos and accurate route planning, which 3m by 3m square a car ends up at makes no difference to efficiency at all, there's actually an argument that it does the opposite.
It's also a great idea in principal but it fails to understand the human interaction, it also fails to understand what is and isn't accessible to a motor vehicle. That reduces efficiency (massively)
