Is this your gut/bias speaking, or have you done legwork on the rate of various incidences in Uber rides vs taxi rides, and based upon that seen that the regulation is unnecessary?
The Taxi groups have done a compilation of Uber related incidents[1]; then only got around a dozen for 2015 in the whole world, and that's with padding the numbers by including repeated news.
