</div>Blame the car designers for not using isolated CAN bus segments for the<br>
critical components. Someone wanted some nifty trick along the way (like<br>
limit engine speed if tire pressure is low or apply brakes if tire<br>
pressure hits zero) but then that opens up more holes in the bus as more<br>
sensors have to talk to critical components.<br>
