Sure, there are cordless power tools. I am not sure what you’re saying.

As for your dishwasher: I’m sure it has received surface treatment as the people designing it made the connection dishwasher ——> water in their heads, so you end up with a surface that, while proudly displaying every fingerprint, at least doesn’t immediately pick up surface rust. Or it features one of the 20 types of alloy that are more resistant to rust. That apparently didn’t happen for the Cybertruck.

In any case, what I was saying: maybe plain stainless wasn’t such a great choice for the body of a car. Maybe if you really lean into it and intentionally add to the rust / accentuate the shoddy exterior, the overall design could work as DIY’ed, end-of-the-world, Armageddon - style Mad Max vehicle. I could see that.
