Uber or Taxis
On one hand you hail a cab, you don’t know them they might be a bad guy and try to rip you off. With uber it is cheaper, you get to rate and see ratings of the drivers. But, there is one little thing. You are tracked. Uber tracks your locations, personal details about you. Everything about you, your habits. Really gets rid of anonymity. Yeah I would rather get a taxi and deal with the occasional bad driver, which surely happens on uber too.
True. Pretty soon there will appear decentralized and safer alternatives ;)
