I have reached the unavoidable conclusion that UBER want's driver's to fail. It wants to get a few hundreds rides out of you before the reality of how little it pays or before the ratings system forces you out. No matter how high they set the bar it has to be obtainable. Thus some people can handle the ratings system (3 complaints out of 200 deactivates a driver.) but most can't. You are still learning at 200 rides. In some weird big business way this constant turnover in drivers makes sense. But not for the riders who are stuck in the same immature service year after year.
