Uber - Lyft definitely has made an impact on the declining Taxi industry as we know it. (A surcharge from Uber going to the Taxi companies to recoup there losses)
I am not sure for certain but would assume these service companies having vehicles on the road driven by there owners is a plus for cyclists, and because of the ratings system the good drivers are rated and a standard is maintained unlike the Taxi industry with very low standards.
Hopefully over time this will benefit cyclists as the drivers overall seem to be more responsible and less distracted then the competition. Uber now having so much input with future autonomous driving, the future looks better, Autonomous services will maintain safe road speeds, and also provide clearances for cyclists, the accident rates should definitely decline, limitations on private cars in city centres will eventually lead to the Bicycle again being KING of the Road. :)))
