Yeah, extrapolating on the brake thing seems especially hinky and ill-informed. If you want to have a discussion about brakepad emissions from a Tesla, you should probably be working from real data about how often the brakes are actually applied, or perhaps extrapolate it from service records about mileage numbers on cars when the brake pads are serviced/changed.

I expect Tesla would happily hand you a bunch of this anonymized data since it's likely to paint them in a positive light.
