There’s a simple rule in our LARP community:
Treat an accessibility device as if it’s part of that person’s body, because it functionally is. Therefore, all rules about consent-to-touch-or-interact apply to all mobility devices.
If people could get it through their heads that they need to treat all mobility devices as though they are part of that person’s body, and that consent is therefore needed to interact with the device, that would be great.
