im sorry to break this to you but electric motors are more reliable than combustion engines. they require less maintenance and last longer because of their inherent advantages. and the number of moving parts and lack of explosions/chemical reactions is basically why. you call my argument stupid but you fail to raise a single valid argument against it. all you can say is that modern engines do pretty well, which has nothing to do with how they do compared to electric motors. in fact im pretty sure the reason you resort to name calling is because you know youre wrong...
and brake lines still require less maintenance for the same reason that pads and disks do. balls in your court.
