I do feel like this applies to Uber/Lyft drivers also (at least in SF and bay area). The bonus structure built on X rides per day makes some drivers quite rash.
The only time I felt unsafe inside the car was when my driver drove with his elbows, with the Uber app in one hand and his wife on a different phone in the other hand. He just honked and cut across 3 lanes of traffic on El Camino on Mountain View. He told me later that he used to drive a taxi for years. I chalked it down as a cool story to tell people.later.
