This was actually a joke in the first place in the Discord, but it could actually be nice and funny: have the option to put stickers on your motor scooter and other vehicles. Could be pre-defined locations on it and you could simply load default images or upload your own, just like canvas in condos.
It would be nice if we could extend this feature to being able to place stickers on all vehicles (like the bottom of a skateboard deck).
If we were really pushing it with stickers, maybe they eventually get some CS:GO-esque sticker features (where you can scrape them off and some stickers have a fancy design post-scrape). Holo and Foil stickers could also be nice.
