This is not an issue in some areas and dry climates as a rule but in the UK it sucks owning one.
I don’t own one now. I drive a little French go cart then I use my legs for off road. They last longer, don’t go rusty and run on dried fruit and sandwiches.

Isn’t it the other way around? Aluminium has a lower reduction potential than iron, so the aluminium should be the first to go. Even lower than zinc, which uses the same mechanism in sacrificial anodes and galvanisation.
I once had the idea of attaching “sacrificing cathodes” made of iron to aluminium beverage cans to make them go away faster when discarded in the environment, but that just causes more problems than it solves, so it’s better stick with container deposit schemes.
Part of me really wants to try it out once, though.
