I would have thought in the future all kinds of traffic circumstances would be handled by broadcasting information (such as "slow down") in a format native to the onboard computer. Then the guy in the hi-vis suit is just a redundancy for humans.

So now this is a signing/crypto and signal reliability problem, which is a bit harder. But still doable.
- ignostic 13y agoEasier said than done. What happens when the power goes out to the city's system? Can we trust the city to keep traffic info up-to-date? What happens when there's too much interference? When you're in a tunnel with the roads broadcasting above you? Self-driving cars are the future, but these solutions that seem simple will still need a lot of work.

They could get get programmed either over the 'net, or by a maintenance truck passing by and pinging them with a cryptographically signed message.
