I found the controls intriguing at first, but then frustrating. I like alternating the pedals, but balance should be accelerometer/tilt based, and braking could be stronger if you press both pedals at once. Finally I think the crank could have a little more intertidal - I often got my cranks stuck vertically, where neither one really goes anywhere.
Somebody has to make the call. There was this dinosaur book for kids in a little free library. It didn’t even have an author or publisher, because it was AI garbage. Full of misspellings, etc. I contemplated throwing it in the trash because I don’t think it should exist. But for some reason I had trouble deciding that for others.
Digitize and delete? Scan straight to OCR and dump the books. One hard drive can store a lot of books.
