ehhh, cars shouldn't be communicating with cars they can't see. but i'd like to them to communicate over free space optical, aimed at the level of other vehicles. brake lights could be modulated to contain current braking force, and reason for braking. turn signals could contain the destination lane. head/tail lights the current speed, and target speed.
- wmf 9y agoNone of that information can be trusted, so maybe it's better to not even bother.
- cortesoft 9y agoInformation that can't be trusted can still be useful.
- mindslight 9y agoNeither can brake lights.
- marcosdumay 9y agoSelf-driving cars can work without trusting brake lights, and I think they should. It's humans that can1t use anything better.
- Piskvorrr 9y agoIf only it wasn't for those pesky humans, all of this wouldn't be an issue. [blocky 8-bit lightbulb appears over robot's head] Seriously, "let's have everyone jump on the bandwagon all at once, and we shall be redeemed by $TECHNOLOGY_DU_JOUR" is a very brave proposal.

- Animats 9y agoCommunicating a few bits over radars is a possibility, like the way TCAS works for aircraft. There's a simple fixed-format message, agreed upon internationally, which is used to negotiate "I go up, you go down" decisions to avoid collisions. One advantage of data over radar is that you have range and bearing info on who's talking to you. At least you know where the info is coming from.
