This was my thought as well. The whole situation seems very unjust. The safety driver was probably being paid minimum wage to take on enormous personal risk, both in terms of their own safety, and accepting full liability for any harm to anyone else caused by a system that clearly was not ready to be on public roads at night. The task of being a safety driver is impossible from the start. I doubt any human is able to pay full attention for a long period of time while not actively engaged and be ready to react within milliseconds. Uber knew that. Why else would they have a camera pointed at the safety driver unless the whole purpose was to pin any blame on them?
