Hey Stefan it’s very nice to meet you! I spent many years at GRASP lab at UPenn and most of my friends from there are at Waymo/Nuro/Cruise now. I do not work at a self-driving car company, but I 100% agree with your sentiment regarding the importance of assessing safety, this has obvious implications in how these cars are insured, and therefore priced and financed. On a separate note, I met a long haul trucker/Russian immigrant in a hacker hostel in Mountain View, and his story was eye opening. He said it was the worst job he ever had, and he was “treated like an animal”. So alleviating his problem is very worthwhile in so many ways. As for questions:

1. Referencing page 5 of your VSSA (1), how were you able to quantify "When weather, traffic or other conditions made driving unsafe." It seems like a tricky problem because this region of the ODD is not discrete such as {warehouse, ramp, highway} but rather depends on the quality of your cv stack as well?

2. In hindsight and with the company behind you, do you think it make sense for each car companies to do self reporting? Or should there be some sort of government oversight/technical validation process done by external 3rd party?

3. I would love to chat more! It must be a very emotional time for you, so I would understand if you do not wish to speak about it. But if you do, could we set up a time at lingxiao@seas.upenn.edu?
