I don’t live in the snow so never tried in real life, but local laws usually classify different levels of two wheeled vehicles. Some laws treat level 2 and under, where most e-bikes are, the same as bicycles. Mopeds and motor-driven cycles are a level above that are allowed on surface streets the same as cars but too underpowered for the highway. Then the level above that is the traditional motorcycle that are allowed on streets and highways.

tl;dr, it might be allowed for e-bikes to have studded tires depending on how local laws classify it.

Buy an electric bicycle and use the money you would have spent on a car to run for a seat for local office on the platform to improve local transit infrastructure

Its cool to see people thinking about how to donate when they can. I think about it as well, and when I have donated I think most if not all fall into your list.

I used to use nitter to view stuff people sent from twitter. Now I guess I won’t ever look at twitter ever again.

If you want to try some niche music service there is resonate.coop which encourages exploration by making it cheap to listen to a song once. However, if you like the song and keep going back to it it will be considered “purchased” and you will no longer be charged when you listen to it. Last I checked there was no offline mode for purchased songs but they were working on it.
