Only 4 things to know with electric car then? maybe add don't forget to plug it in.
Chevy Silverado electric truck: no antifreeze/water to top up or replace no perished rubber hoses water pumps to replace , no more expensive cacogenic smelly front axle oil/transaxle oil/rear axle oil/transmission oil/engine oil, no more oil filter, air filter, fuel filters to replace, not more rotten exhaust system or expensive cats to replace, no valve clearances to adjust or reshim, no spark plugs, glow plugs or leads to replace, no more fan belts or timing belts/tensioners to replace.
I like the idea of just 4 things to check sounds great to me.
Checking the condition of the tires are the most important important thing to me, and replacing them is about the only job l don't do on a car myself. Checking brake pads/brake shoes changing brake fluid every few years, wiper blades and topping up washer fluids, tire pressures routine maintenance on an electric truck life made simple l could live with that,
