Summary:

• Self-driving cars collect a massive amount of data, including visual and other information.
• This data could be used to track people's movements, which could pose a threat to privacy.
• There is a lot of uncertainty about how this data is stored, secured, and accessed.
• Law enforcement agencies have already served warrants to self-driving car companies for footage.
• It is important to have strong privacy laws that address the data collected by self-driving cars.
• We need to know more about how much footage police request and how companies respond to these requests.
• Regulators need to consider the civil liberties implications of self-driving car data collection.
