One common misunderstanding about the vehicle network data is that it is limitless. The truth is that the only data on the network is the data that is required to be there. Nothing more, nothing less. What is required is different from vehicle to vehicle. For example some vehicles might have adaptive cruise control and this system might require vehicle dynamic information that is not required on vehicles that do not posses this system.
More and more data is being added to already heavily loaded networks, so automotive OEMs are adding more networks to accommodate more data. Good news for us, now we can get more info at higher data rates.
