Something that can be sprayed on driveways, sidewalks and possibly lawns that makes it impossible for snow or ice to remain, I HATE shoveling.
I want cars to come with car seats that automatically convert into child carseats and back again. Moving carseats around and making sure they are properly installed is a pain, having them custom installed would solve a lot.
So far, I am loving the pantry/recipe idea, the chip with all our medical info invention, and the autopilot/track for car travel ideas!! Great thread idea BTW!
