Electric fans burning out the fuses

[Michael C Henry]

I've watched the old electric motors with brushes being replaced with brushless motors. The fan in my gas heating stove, then the Dewalt cordless drill drivers. why not electric fan motors on cars? They are more power efficient than the older brushed versions. Why wouldn't the brushless technology eventually be used on electric fans for cars? It may already be available in a better brands, Again I do not know I suppose then there are warehouses' full of the old fan versions, yet to get rid of.

My SPAL puller is brushless, as is almost all of their fans (but not all), but my pushers use brushes.
