Exactly, at 1mph, almost all drag is rolling resistance. This statement is of no use.
"No one has been able to show any data on BEV cooling drag as a percentage of total drag that rebuts what I wrote in the first post."
Julian, while I agree, it may be worth specifying
aerodynamic drag, because total drag is both linear (rolling resistance) and exponential (aerodynamic).
aerohead is correct when he writes that at some velocity 1.4% of total drag is cooling, however that includes rolling resistance. Ignoring rolling resistance is essential to get correct numbers.
