Vespucci seems like the best option besides osmand. http://wiki.openstreetmap.org/... https://youtu.be/FnU-b6EZ_sE?t...

Gas + wear&tear is not that complicated to at least get a good estimate. What Uber charges is going to be far above that otherwise not driver would operate for them

Every German that has been trough the TÃfoeV (http://en.wikipedia.org/wiki/Technischer_%C3%9Cberwachungsverein) can tell you that they don't joke around. They often send regular drivers home and tell them to come back one everything is fixed. I don't see why this should be different with cabs. The main difference is bascially that they have to do the chech more often.

The problem is that they are building small almost monopolies, which basically forces you to use their services, especially if you are on the business side of the whole thing and want to be found online.
