I think Long Can network wires can be problem but you have to understand what is "Long". CAN spec says 40 meters, does typical FRC robot have even 8 meter of CAN wire length?
CAN is differential signal so as long as you have twisted pair and proper termination resistor you are good for FRC use. if your network is in manufacturing shop floor then you are in totally different situation
