It seems like it would be useful if there was some standard for actively notifying autonomous vehicles of something they need to be aware of. For example, a bike light might also transmit a radio signal to the car, or perhaps it includes lights operating with a specific color or pattern that self-driving cars can look out for (maybe it doesn't even need to be in the visible spectrum). Obviously this needs some thought. For example, how would you prevent people from messing with the cars - maybe it's very short range, or line-of-sight only?

In the end, the "messing with cars" problem renders almost all explicit-communication-between-vehicles moot, or at least not as useful as people first imagine. The autonomous car will still, no matter what, have to trust its 'vision' over any informative messages. This is not any different from cars driven by humans, btw. Someone can put up a sign (say a merge left sign and some pylons) that can cause accidents pretty easily, which is why drivers still have to pay attention. The thing is that wide, let alone 360 degree, vision should provide the computer with more and more useful 'messages' than humans are ever capable of taking in. And probably more than any attack vulnerable information messages could provide too.

  Yes, though I can't recall any incidents where someone set up traffic signage to intentionally cause an accident (I'm sure it's happened, but I bet it's really uncommon). Anyway, I'm not suggesting that the car take a remote signal on blind faith, but I still think it might be useful to have some kind of indicator. It can be factored into the other sensor data - "this signaling object does appear to be in close proximity and moving like a cyclist". Just as people don't tend to mess with signage and cause crashes now, I think they're unlikely (on the whole) to do it with these kind of signals. Especially since you'd be in serious trouble if you caused a wreck.

    Well, keep in mind how much harder might be to catch someone messing with traffic with radio signals of some sort than by physically being present and visible and putting nonsensical signs in the road. I do think it would be more common.
