+ "Unsafe everything, assaults [and] kidnappings" are in fact already illegal. More regulation will not make them more illegal. Claiming we need a taxicab commission to enforce basic laws is a non-sequitur of breathtaking scope.
+ There was a vibe that Uber will compromise the customer experience to make more money. This is nonsense, uber is operating in a cut-throat environment where any cost savings will be passed directly to consumers who are getting what they pay for. As one questioner pointed out at the end, Uber isn't actually making a profit. Any cuts in quality are being passed on to the customer in reduced fares.
+ Insufficient insurance. This one is one that is up for debate; but the message of 'insurance good, profit bad' is probably oversimplifying the issue and likely pushing an outcome where everyone has to pay more for transport without a proportional improvement in outcomes. The speaker might feel better about that, but I doubt the Uber passengers would.
