Nobody ever tried to use CAN for streaming video, because that’s not the purpose of CAN?
> Tesla’s next-gen networking is all about timing - and unlike CAN, where two messages coming in at the same time can collide (resulting in neither reaching the node),
> CAN is like everyone yelling in a room
This is simply false. CAN uses bit arbitration and the lowest address wins.

- detaro 2y agoThe cameras often have dedicated cabling to the front. Sometimes analog video (probably not so much today, or only on the cheap end), sometimes digital over Coax. In other cars its using Flexray (which is a high-performance bus-system designed to be able to also support video)
- detourdog 2y agoI'm also sure somewhere Doom is running on CAN.
