| Shopping trolly for car-free living
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.Reward: one such

| Smart Stop Signs
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!Reward: recognition
