The CAN hardware can handle two drivers sending at the same time and the 
protocol detects this and handles it gracefully.
I never used RS485, but what I read it looks like the programmer has to 
avoid that two transmitters are sending at the same time. Also the RS485 
transmitter cannot detect that another transmitter is active.
So CAN is better when there are multiple independant data sources. CAN 
does error detection and retransmission. RS485 is just a serial link 
with no error checking or correction.
