Sounds like a killer app for VR- observing from the driver's perspective, being able to switch to whoever you want. How many cameras are in those cars I wonder?
They have a lot of cameras and they offer a paid service where you can stream from any driver's onboard. Unfortunately this is out of sync with the main broadcast which kinda kills its value for me...
I think VR would make most people sick as it's a very bumpy view.
