The networking on AVs is usually redundant across multiple cellular networks to deal with coverage and outage issues. They also use business sims, which usually have a slightly higher network priority than consumers. If waymo's also negotiated to use one of the infrastructure QCIs instead, it would take some seriously disastrous network conditions for them to experience meaningful congestion.

- AlotOfReading 10mo agoBandwidth is problematic for mesh. A remote assistance situation would involve at least 4 high definition camera streams, and ideally with minimal latency. It's challenging to put that much data onto public spectrum even if you wanted to make a custom radio.
