Drone police ticketing ~

Highway Patrol troopers could have a drone to launch that would chase
and land on speeding vehicles. It could magnetically attach to the
roof, trunk, or hood and alert the driver through sound, lights, and
signage to pull over. Trooper could then have a view of the driver and
approach based on what is in view.

Yellow brick road ~

Make a way for navigation apps and devices to turn the path you're
following into a yellow brick road and the vehicle icon ruby red
slippers or a hot air balloon.

Wouldn't that be fun?

Laser screen door ~

Use lasers as a screen against bugs.

I know that they have used lasers to directly shoot bugs, but could
you set up a screen and zap bugs as they come through the window or
door? That way you could set up a screen house and still have an open
door to let the breeze and the bugs would use came through the door.
It may not kill them but it would still about a cook most of the way.
And that it could also turn off without human or animal approach to
turn back on when it was clear.

AR car transponders ~

Augmented reality idea: Transponders on cars would allow other drivers
in the police to see tags above the cars and tell if they're speeding
or not just by the color of X.

You can also get the identification of a driver and everything just
inside the augmented reality glasses or headset.

And then just a button to send him a ticket or indicate to the driver
that they need to pull over.
