Police patrol AI ~

Make the car into a robotic officer the as the human drives the car
around reading the tags that are within its line of sight and
correlating those tags with the type of car that they are registered
for. If there is a discrepancy between the information with the tag
and the actual physical type of vehicle the officers alerted about it
and can choose to investigate further or not.

Police cars are out in the community all the time and so you could
have an officer driving through a neighborhood and with the onboard
electronics scan pieces that it can see and correlate them with
locations known where those faces are normally seen. And if there's
something terribly out of whack the officer can be alerted and can
choose to investigate further

Invasive but they're already hidden amongst us so why not use them?

AR dog ears ~

Make AR and VR goggles able to overlay faces with dog ears. Then give
them dog ear reactions to the direction you're facing, when you enter
a room, when you raise your voice, etc. Bonus if you add a tail to
people!

Train car ads ~

Why don't trains and shipping companies have ads on the side of their
rail cars? They could easily sell ads or advertise their shipping
company a little bit more than just putting their name on them.


They could even encourage graffiti artists to fill in the blanks and
then the graffiti artists could sell whatever they're doing as long as
they subscribe to the railroad car. Just an idea.

Extra arms ~

Extra static arms on a waistband

Kind of like a Dr. Octopus rig where the harness goes around your
torso to position two or even four positionable alarms to hook/hang
something on or something to support something you're carrying. Two
or three points of articulation for trays of food or multiple tools
for something hot without burning your fingers. You could even put
hooks on them so that you could hang stuff off of them like gloves or
tools.

Then if you start put in attachments to hold you could actually lean
your body in to drill hole was turn things something to pursue until
you can come up with a fully articulated set of arms that you could
put on with the battery pack that move around your voice command and
eventually your mental command.
