For the folks wondering about Plaid vs Dragstrip mode here are my observations based on videos I've seen so far and how my Raven Model S worked. Hope this helps some other launch nerds out there.
On the Plaid Model S, you can select "Plaid" under "Acceleration." (This is very similar to how you select "Ludicrous" in the Raven Model S)
If you want maximum performance and launch/cheetah mode, you select "Plaid" and then "Drag Strip Mode." D.S. mode can only be used while in "Plaid" acceleration.

Then on the binnacle display this display appears. The yellow pill says "Drag Strip" with a rocket icon. Under that it says "conditioning for Peak Performance, xx minutes remaining"

This process is very similar to how the Raven Model S Ludicrous+ mode/launch/cheetah mode works, except the battery heating information is included on the main display as seen below.

My big question is has Tesla improved the battery heating time in the new Plaid? With my 2020 Raven, it takes around 45 minutes of battery heating for the first pull and then 5-10 minutes between pulls for the battery to be at the correct temp. I'm really hoping that Tesla dramatically reduced that.
