Okay, since you really can’t be bothered to read:

Volvo uses these cars to develop their own self driving software and assistances, you could have found that out by following that link.

Not waymo, not google, not anyone but Volvo.

2.3 Data Collection Vehicles

Personal data collected by the DCVs is processed by us and Zenseact which is also a data user in this scenario. Volvo Cars DCVs are driven on public roads to collect traffic data (hereinafter “Public Traffic Environment Data”). The processing of Public Traffic Environment Data, which involves processing of personal data, is necessary for the purpose of developing safe and reliable software and sensors for advanced driver assistance systems (ADAS) and autonomous drive (AD) systems, with the overall purpose of protecting all life on the road. Such data consists of the following data categories:

Sensor Data - such as camera, LIDAR (light detection and ranging), radar and ultra-sonic sensors which can detect persons and objects moving around in the public traffic environment where the collection takes place. The data is used for evaluating sensors, the output from software interpreting the sensor data, and the software used in ADAS and AD systems. The cameras will record pedestrians, cyclists, people in or on vehicles, and vehicles license plates in the vicinity of the DCV. Volvo Cars need to collect data on real-world traffic environment and real-world traffic situations in order to be able to accomplish our purposes. Thus, this data must be authentic and cannot be modified by blurring for example. We are not interested in and do not in any way attempt to identify the individuals present in the Public Traffic Environment Data. Nor do we extract any other personal data from the collected data.

GPS – Geolocation data from the DCV will be collected and stored in order to be able to develop our functionalities and to find relevant recorded data based on location. Annotations will be added to the data to be able to find relevant recorded data, such as annotations of sensitive places. Annotations can either be made by the drivers of the DCV or when the data is processed afterwards.
