No oil changes. No finding a gas station just to refuel. No worrying about whether the engine is warm enough for setting off in the morning. No smell before the cats light off. Instant heat. Instant torque. Dead silent. The list goes on and on.
After you get used to it, the idea of going back to ICE again is unfathomable. Why would I want to give up the convenience I have now? For road trips? Ha! I have both ICEV and EV at the moment and it is the EV that is the preferred road trip car, not the ICEV.
It may be true that when 30% of vehicles are EVs, oil change locations will be hard to find, but I doubt it. Even if dedicated oil change chains cease to exist, people will still need tires, alignment, etc, and those shops will presumably provide oil change services.
Regardless, it's going to be a while before 30% of vehicles on the road are EVs — isn't it like 1-2% of new cars sold? If vehicles stay on the road for 20 years, then EVs won't be 30% of the total fleet for a long time.
