Why are you guys talking about brushes? Any serious EV is either AC Induction (the Tesla, tzero etc) or is AC PM, either way... there are NO BRUSHES!
About the only mechanical part to wear out on an EV using in-wheel motors is a wheel bearing. Compare that to the long list of common heat related component failures on ICEs and the auto service and spare parts industry will basically vanish as cars fail less and require NO servicing! Bring on the 3.5 Million mile car (pending battery life)
Yeah. If you're EV has 200+ horsepower and you flog it around the racetrack and public roadways, your brushes will last around 15,000 miles. In normal driving with modest acceleration, those brushes will last around 100,000 miles. Vrushes are cheap, about $20 to replace and take around 15 minutes or so to replace yourself. Lot easier than an oil change, apparantly.

Well, I think that includes replaces some parts in the motor. Like brushes or bearings.
The big problem is the lifespan of the batteries.
