I say Bjorn should get the new version and beat the heck out of them. He sure has killed his signature X's white ventilated seats! Just did another demo of how bad they look, but I think the current Ultrafabric material is really different from the original/old version. What they use in new ventilated seats is another whole question.
Seeing his seats is exactly why im not at all upset about not having ventilated seats. Didn't Tesla discontinue them due to a lot of problems with efficacy and longevity?
