Peer to Peer Networking for Road Traffic
alecclews writes "The BBC is reporting on some German research to allow the exchange of information between road vehicles about travel conditions using peer to peer networking (I assume some sort of mesh). Cars or bikes experiencing problems would pass data that would ripple down the chain of vehicles behind them. 'For example, cars could spot oil on the road by combining temperature readings with wheel traction information. A wheel slipping on the road even though the temperature was not low enough for frost or ice would suggest oil or another slippery substance was present. Once a car detected this sort of danger, information about it would be generated and passed down the line of vehicles approaching the patch of oil.'"
Could prevent pileups at the least. Of course anyone with such a system could potentially be tracked.

Now any idiot with the right cantenna can bring any highway to a crawl by inserting bogus messages into the mesh. "Look out! Slippery road. Warning, stopped traffic ahead. Pull over, emergency vehicle approaching from behind. Look, Elvis!"

I've been thinking about this one on occasion for a few years now...
The only things that need be passed along are current GPS location ( deliberately imprecise by about 20ft ), current velocity ( deliberately imprecise by about 10mph ), last 5 secs acceleration on all 3 axes and a time stamp.
The other function that a car should do is listen to the traffic going the other way and pass on an average of what it hears. ( This averaging function is crucial. It enables velocity and location to be reported without giving up evidence of speeding.
As an example: northbound traffic reports the four pieces of data. Southbound traffic listens to it and averages it. A minute or more later the southbound traffic repeats that to the northbound traffic who are soon to encounter the situatuion. It keeps repeating it - interspersed with other data about other locations - with decreasing frequency as it gets further away.
So you think IPv6 suddenly means auto manufacturers will stop being so proprietary?
Saying Java is nice because it works on all OS's is like saying that anal sex is nice because it works on all genders.
.... would come from VoIP connectivity between nearby vehicles. We wouldn't be as prone to road-rage type behavior if we could easily speak with people in adjacent cars. If I could say, "Ahem, excuse me," instead of tailgating and flashing my headlights at the idiot camping in the passing lane, both his and my blood pressure would benefit.
A lot of dangerous/reckless driving behavior comes down to the dehumanizing nature of cars. If you see traffic as a collection of people and not anonymous metal cages, you'll be a more considerate and safer driver.
Automatically spotting and checking for oil on the road... yeah, I guess that's cool, but it's not the most important use of this tech.
I know why I'm posting to /. on a saturday night, but I think you just made it blatantly obvious why you are...

We once had this idea for a global voice network. Everyone would have a number and accept calls by default, and people could talk to each other. One guy on Slashdot knew better, though. He informed us that people could call businesses with bomb threats, for example, and disrupt the economy. Adults could call children and try to abduct them. Random businesses could harass individuals with marketing calls. Loopholes abounded and there was no way to fix the system without breaking it more.
We would have called this a telephone network, but we had to give up on it since its security was obviously so flawed. Thankfully that guy on Slashdot saved us all that wasted infrastructure money. Nothing good would have come of it anyway.
