I watched a fascinating talk a couple of years ago by a guy who learnt in detail how various cars' computer systems work and communicate, (mostly by studying them directly, and reading the chip info when he found out what they were), connected to them, and eventually could play racing/driving video games with his car i.e. with the steering wheel, pedals etc. I can't recall the name, but I'm sure that would be useful and answer most of your questions. Maybe someone on here will know the talk I mean. (Can't see it on googling 'hacking cars talk' videos 20mins+ .. but that finds some interesting stuff)
