Does the spoiler on a Model Y actually do anything or is it purely cosmetic?

Protects the deck lid from scratches if you open the hatch under a low ceiling.

Actually, takes the scratch that would have otherwise been on the deck lid - ask me how I know...

It definitely do things at high speed, but of course not as much as those on a F1

It sure does. It flops around once the tape used to adhere it to the deck lid comes loose.

It is purely cosmetic.
