It's just uber's job to comply with all regulation. Insurance, training, safety, etc. Generally those laws are in place for a reason. Claiming they are a "ride sharing" app to avoid commercial transport regulations is disingenuous at best.

Edit: Obviously artificial quality reduction legislation is a bad idea, but uber as a company has been pretty adamant about ignoring all regulation. Even if it is a bad regulation you don't ignore it, you lobby to get it changed.
