A Shabbos-friendly mobility scooter. Reminds me of a PBS program I saw on an Orthodox Jewish hospital where the phobes were rigged with an elaborate hole and peg dailpad allowing one to dial without breaking the rules (it used a light that was interupted by the peg which was analogous to a fire blowing out if you opened the door). Truly Rube Goldberg.
Including the FB post I found this on so you can read the comments should you be interested.
