Hmm, my jury is out on Uber
Cote do you think satnav is 100 per cent reliable. Ime Uber drivers follow it religiously, when it often takes you the long way round, shows no knowledge of short cuts etc. Drivers will usually not listen when you try to tell them the route, it can be very frustrating and cost a lot more than it would with a driver with a basic knowledge of the area. However,the longer they drive, the more they should improve.
They also often do a 1.5, 2. 2.5 per cent surcharge and a minimum fare, in my part of London at least, which makes them just as expensive if not much more than a black cab.
Otoh, I like the fact you can usually get one quickly and when price points are normal it's good value. I very rarely use black cabs because they're so pricey so it's not like they're losing my business, as they didn't have it in the first place.
