Why I can't wait for affordable electric cars

I am sick and tired of paying repair bills for internal combustion engines. Water pump went out today, mechanic said might as well replace that timing belt, serpentine belt etc. Should probably fix that annoying oil leak while your at it. $1,600. Think of all the things that break on these cars: cooling system, lubrication system, valves, pistons, crankshaft, heater core, transmission, CV joints, belts, hoses - on and on. I'm thinking these all electric cars will easily go 300,000 - 400,000 miles without issue. Sure you'll have tires, maybe a new battery, other minor stuff. There is a whole economy around internal combustion engines, auto parts stores, mechanics, customization etc.
