having been dealing with CAN and other network controllers on within the motor industry for as long as i can remember i take it for granted that you can just make a car do such functions people have never even heard of
though it is rare to find people interested in such comms networks really in day to day life, then when you tell a customer how the systms on their vehicle works, and what gives/receives signal under address words they sort of look at you as if to say 'yeh ok' and theyre not sure if your just talkin crap.
it is a major development though for motor vehicles, we have been using can in the mainstream for circa 25years (automotive) yet only in the last 5-10 has it become really interesting
