Shopping trolly for car-free living Printer Friendly Version
It would certainly increase the number of people shopping without using their cars if we could take large shopping trolleys from the supermarkets strait to the doors of our homes. The trolleys probably need to be a bit more tough for this purpose and to have an rainproof cover (like on a pram). Also a deposit would probably be needed to be paid at the shop.

Smart Stop Signs Printer Friendly Version
I noticed how most of the time when I pull up to a stop sign, there isn't anyone else there, yet I stop anyway. Why? Because its against the law to not stop at a stop sign.
This is a complete waste of fuel. Perhaps sensors on the road could alert someone that another motorist is going to be at the intersection and thus activate a stop sign alerting the other motorist they are going to need to stop. Otherwise they can just cruise on thru, thus saving fuel!

Windshield Wiper Snow Sensor and Raising Mechanism Printer Friendly Version
Today's cars can measure outside temperatures and they can also detect precipitation or snow. In these conditions, the windshield wipers will automatically raise off of the windshield by 10mm. This keeps them from freezing to the windshield when parked.
