When I say, "It took this long?" I mean that a completely unregulated livery (taxi) service went this long without some Uber driver or other comitting a major crime upon one of their 'customers'?
In many countries regulation consists of mandatory training, extra drivers tests, advanced first aid courses, etc. Most companies requires a clean criminal record (well they review the record, in case of severe crimes). But in many countries entries on a criminal record also expires... These are not guarantees.
Either way, I feel more safe using Uber because there is an electronic record on everything linked to credit cards, car registrations, etc. So if a driver robs me tries something funny, filing criminal charges against the driver is easy. A random cap driver on the other hand is hard unless you're quick to memorize a license number.
