Re: Obviously the solution is....
I had a thought that started out silly - "ha, no you want automated Segways"
Then got serious.
Automated wheelchairs. Person who can't control a chair but could control an adapted app could set a destination, "Take me to Argos / the pharmacy / Waypoint 3/ somewhere accessible for lunch". Chair has all the automated car mcguffery but can also go in pedestrian areas and can use your big company AI to take the client where they need to go.
Could update 'things' in shops too, "Mr Smith will arrive in 5min, he'll need some help to pack his prescription", "here is Mr Smith food order".
One of my less stupid ideas I think.
