Version 5.11 of the firmware has changed the HVAC controls so the fan now only goes to 10. Previously, it went to 11, and as we all know, that's 1 faster than 10. When we needed that extra kick of cooling, where other cars maxed out at 10, BOOM! we could go to 11! I know... you are probably saying "In this new firmware they just made 10 the fastest setting." The flaw with that is that 11 is one more than 10! The volume control still has it right... when we need a few more decibels... 11! So, I humbly request: BRING BACK ELEVEN! Sure there those out there who may have been surprised or confused that the the fan went higher. Of course they are more confused now that the volume does and the fan doesn't. Is the answer to this to make the volume control 10 also? Duh... of course not. Is it a serious issue? No. Will some people not up on their cult-classic movie watching scratch their heads? Yes. Do we want Tesla to lose the fun little easter-eggs that help set it apart as a fun company and become stodgier over time? No! These are the folks that came up with "frunk". They (along with SpaceX) have a datacenter named "Cyberdyne Systems". The DNS name for the computers the model S talks to is "mothership". Elon just made a "Nobody expects the Spanish Inquisition!" reference in an interview, and recent posted a blog entitled "All our patent are belong to you." Please.. don't lose the slight irreverence on the way to growing up to be a big car company... BRING BACK ELEVEN!
