Comment on Killing car privacy by federal mandateparent

The most basic safety feature is that cars can tell each other when they're braking, so your car can start braking the same millisecond, not when you happen no notice things.

Maybe the car should emit some sort of electro magnetic radiation signal that can be detected with a sensor. It could be emitted when breaking. It could even be part of the visible spectrum so we could see it as light. Some sort of breaking light or maybe just break light. Too bad no one thought of this earlier.

Are any of the TCP congestion control algorithms dependent on a router's TCP receiving messages that are trusted by the router to be originating from upstream routers based on an authentication scheme that the router manufacturers trust to deliver anti-DDOS safety features?

Much more likely to be UDP.

Would you say that such a UDP-based scheme is safer than TCP?

It's designed for such applications where timely delivery is more important than its confirmation and old data is useless.

Safer? In the timeliness sense yes, in the delivery of important info yes, in the reliability of each packet no.
