In Paris (I think, again anecdotal and I only used UberPop on my most recent trip to Paris) UberX are "citizen drivers", but meeting semi-professional standards in both their service and their vehicle. UperPop, at least feels to the consumer, like someone with a small car clicked a button saying "yep I can do this" and voila, off they go.

yeah uberx are still following uber's guidelines and are pretty professional. if they fuck up too much uber terminates their license.

uberpop is basically everyone and their dog, ie this is closer to real ride sharing.
