Definite mixed feelings about this; US DOT has been studying V2V comm systems that will allow vehicles to to keep tabs on each other. Read about it here; http://www.its.dot.gov/research/v2v.htm I sure hope aftermarket boxes are available, 'cause I don't want to be riding a moto without a transponder in the midst of a bunch of drivers who figure they don't need to pay any attention to what's going on around them because the computer will warn them. OTH, if it could eliminate or greatly reduce SMDSY's, I'd be all for it. What are people's thoughts on the pros and cons of this? I can see benefits for bikes if the bike can transmit it's position to the cars nearby. What about cars telling the bike about their presence? At stop lights, for example? Yes, WE'RE supposed to be paying attention too, but sometimes attention slips. Do you see benefits for car to bike V2V?
