Hi LP, I too sometimes find Uber frustrating. Similar xperience in London on a couple of occasions where the vehicle says 1 minute and then it seems to have gone past me and way up the road, only to turn round and come back for me ten minutes later. I think the problem is that with the old fashioned mini cab we don’t know when the vehicle is depatched nor on its way, so we don’t know it drove on by. With GPS tracking of the vehicles on our smartphones we do know. On the whole I find Uber pretty good.
