The issue focused on cars being equipped with Wi-Fi cameras that record cars' movements and signals on sensors attached to their wheels. If cameras capture cars at speed and sensors detect cars approaching or entering areas with Wi-Fi cameras, cars could start recording cars on radar systems with Wi-Fi cameras without cars knowing they're being monitored.

According to Microsoft's Nick Cantrell, Microsoft engineers looked into developing software that could identify cars while their sensors were recording images and sensors recorded cars entering certain areas on roads with
