I live in a place where the rubbish doesn't get picked up, you have to take your waste to a central location where it can be processed. Part of that, but not required, is making the effort to separate items that can be recycled from waste.
I can't really process the concept that an emergency situation is smoke pouring from under the hood while getting the car washed.
With that said, if you have a handicap or need/want any kind of assistance while I'm around you, I'll stop what I'm doing and address the more important things.
One world, some people live the concept.
More than once and with different people, I've actually experienced your scenario of a not fully mobile person falling and having issues with getting up. Having a phone works, the additional "features" serve no point.
Perhaps you can define how "glass" will change the ability, or lack thereof, to get off the ground.
