Rolling resistance isn't friction.
You might be confused by the fact that "rolling resistance" doesn't include drivetrain friction, wheel bearing friction, motor friction, etc. A car with its parking brakes on has a lot more resistance to motion than one in neutral with the brakes off, but that's not "rolling resistance".
