I'll back you up on the electric motors being more reliable than gasoline engines. Gasoline engines by design have all sorts of moving parts where there is sliding friction mediated by partial lubrication[1]. Wear is inescapable.

Simple math gives you an estimate for the max run time of a gasoline engine.

200,000 miles / 30 mph => 6600 hours.

So after 7000 hours of run time a gasoline engine is shot. Industrial electric motors easily achieve run times that are ten times that number as do the power electronics needed to drive them.

[1] Partial lubrication means you have metal to metal contact. Full lubrication ala a pressure fed journal bearing is a different story. There the bearing surfaces are separated by a film of fluid. These types of bearing can an do last for decades.
