First, Samantha, who writes:

I have an engineering degree and you don't fool me for one second. The engine (in an IC car) is by far the most expensive part of the car. In electric and hydrogen cars, they're maintenance free. You're selling horses in the dawn of the age of the motor car.

I'm not selling anything, Samantha. Nor trying to "fool" anyone.

I never claimed the engine in an IC car isn't "by far the most expensive" part of it. Do you know what a straw man argument is? I did state that in an electric car the battery is extremely expensive.

Which is inarguably true.

I also pointed out – in re your original question – that electric cars are not (as you claimed) lower maintenance than IC cars. Maybe the electric motor is – but that is only one part of the EV. Aside from the motor, EVs have many of the same maintenance issues (e.g., wear and tear on brakes ands tires, suspension components as well as the cooling/heating system for the battery, which isn't] easy for the average person to deal with; in some cases, the EV's body must be lifted off the chassis to access these systems, etc).
