I agree Bert this is posisble to accomplish...and km to miles conversion is so dumb simple that I am still amazed that multi-million dollar programs trip over this (including US rocket launch)...but car is a car, I want 100% probablity that it will drive, not 99% like my PC working or not 95% that WiFi will be working (I was visiting a major US University recently and my laptop would refuse to read emails despite having correct PHY connectivity, probalem was at the MAC or higher level of hierarchy)...and I don't want my car operation being dependent on talking to some other car...Kris
car to car talk is the futuristic feature and soon would become quite useful. The standards used and regulation is something to watch for. Also there are so many car manufacturer would this communication be independant of mfr. or each of them would have their proprietary.
