Self-driving car engineer: "detecting cars you can't directly see is a huge problem, what are we going to do about this??"

Other Engineer: "just have the other car tell us. I know you like solving hard general case problems, but come on. This solution is super obvious."

Problem... this broadcast approach isn't particularly helpful unless all cars have it. So to add this TCAS style solution to all cars might cost what? $100/car in equipment alone? For all 263 million cars in the US that would be $26 billion. Seems pricy when Tesla has a system today that solves this problem without all that infrastructure, or the privacy concerns?

the broadcast system is certainly helpful if less than all cars have it. The proposal estimates the cost per car at 100-300 dollars.

Solves it for those cars, and certainly at an expense higher than 100-300 cars. And it will only get better as it gets information from other cars.
