@BMWY Honestly it's not baffling at all, it makes sense from Tesla's perspective.
At a product level Tesla clearly views Track Mode as for the racetrack only. Everything about it screams this. Can only enter while in Park, cooling system always runs at max, disables Autopilot and Nav, etc.
From that perspective, it doesn't make sense to give the Y or any CUV/SUV Track Mode. It's not the tool for that job. When I was doing Track Days I never saw anyone bring a crossover, and I'm pretty sure they wouldn't be allowed by the groups I ran with. Yes yes Model Y should be less tippy than ICE crossovers but it still seems wrong for actual racetrack use.
Now you and I and others here understand that many of Track Mode's features can be super useful on the street, for certain kinds and situations of driving. Probably some Tesla engineers do too, but at a product level, Tesla views Track Mode as just for the track. Unless that changes, I can't see them adding Track Mode to the Y or X.
Also look at the time it took them to adapt Track Mode to the S Plaid with its new tri motor setup. Compare with how long the Y P has been out, using the same drivetrain they already setup Track Mode for in the 3 P. If they wanted to do Track Mode on the Y it'd be here already.
