You want to ensure that both lengths of the positive and negative wires in the differential pair are the same.

It's common practice to ensure you don't have data skew.

Kiet,
At higher data rates that is true. At 1 MPS, the wavelength is approaching 1000 ft. so you would have to fudge the twist by several feet to skew the data.

Definitely true. I've been working on much higher speed busses for too long

CAN is pretty robust.
