I hope someone invents a "coal"-roller add-on that emits high pressurized steam (builds it up for 5 minutes, then releases it when the engine is pressed hard). But it's got to be white vapor not black, as it will need to represent the green nature of what Tesla owners are buying into.

... and give validity to these assholes' hobby by playing along with their game?

yeah that sounds like exactly their attitude, fun but useless.
