he makes some good points.  esp about drum brakes not rusting out as fast as disc due to lack of use b/c of regenerative breaking

Kind of funny given that a few years ago the EU banned rear drum brakes on motorcycles, forcing manufacturers to switch to discs on the rear, even on low powered machines that really didn't need them there. But never expect politicians to be experts at subjects other than politics  ;D There were many bikes that had tiny underpowered  front drums in the 70's, but the rear drum had an excess of power and could always lock the wheel easily if required and was simple and low maintenance. Most motorcycles have discs that are stainless steel or some similar alloy and they don't rust, likewise for the calipers themselves which are aluminum alloy, while cars use cast iron or some form of cast steel which is heavy and rusts but is cheap. Powerful brakes are also good for the environment though, because you can carry more speed at times thus reducing the need to accelerate again. Most features of performance vehicles are good for efficiency too, although for some reason eco vehicles tend to be the opposite and feature rather utilitarian, heavy, un-aerodynamic, poor handling and braking design. I think it's one of the common human psychological flaws you can observe, the "sensible shoes" idea that anything sensible has to be something you don't really want, when in fact having what you want would sometimes be more sensible!
