It's not really about being simpler, but rather that electric has _fewer moving parts_. A modern gasoline car has hundreds of moving parts while an electric car has more like 1-4 moving parts (the motors). This means that the electric car is simpler to maintain. Think about all the important car maintenance items you have to pay for. Oil changes, belt replacements, transmission fluid changes, spark plugs, etc. On an electric car, you have a much smaller list of things to worry about. Basically you only need to replace the battery and the tires. Battery replacement should only need to be done every 5-10 years and tires should wear pretty much the same as in a gasoline car.

- neon_electro 11y agoAnecdotal evidence here - I drive a 2013 Nissan Leaf, and with its "B-Mode" (a drive mode that engages regenerative braking more strongly when you let off the accelerator pedal), I can do much more "braking"/slowing down in regular driving without engaging the friction brakes. Frequently, when approaching a stop light I can simply let off the gas and coast/regen down from 45mph to 15-10mph and then engage the friction brakes to stop.

- sliverstorm 11y agoI can't help but point out a spark plug is not a moving part.
- zardo 11y agoIt is an ablative part though.
- avn2109 11y agoThere is a (small) spring-loaded reciprocating mechanical element - aka a moving part - in many (all?) spark plugs [0]. Lubricating this reciprocating interface is an active research area.
