Cameras or Lidar?
So, ARM chips inside? Don't care. What I want to know is what sensor technologies are going to be used!
Waymo is using Lidar, accurate but impossibly expensive. Lidar is great for close-up obstacle avoidance but gets even more expensive if you want 1-second notice of an obstacle when you're doing 130KM/h.
Tesla is using cameras, which are cheaper and should be similar but better to human eyesight. Tesla add a normal radar, but I'm not sure if they know what to use it for.
ARM has reference platforms for handling video feeds in an automotive environment, I don't know if anyone has picked it up.
More details please.
