| Transportation Safety 
A rail evaluation car could be developed to travel far enough ahead of any freight or passenger train averting a rail accident. The evaluation or "monitor car" would be un-manned and have the abilty to feed real-time data to the engineer and also to record track data for later reference and evaluation. This could save lives at train crossings and by advising the engineer of a possible derailment.

| Automatically control speed limits
Have something put on every city block that emits a signal that tells the car what speed it can go up to in that area. Also have all the cars in the U.S equipped with a "receiver" and some kind of a governor that adjusts according to the signal received. To make sure the chip in the car isn’t messed with you could have them checked every time you get your emissions checked. Also make sure the emitters installed on every street checked and also have them pick up the cars that don’t have a chip installed and report them.

| Universal spare tire
I searched google, and it looks like there is a universal spare tire already in production. However, they could also be stocked at strategic locations along the roads; at locations like emergency phone / wireless internet connections. By not having to carry a spare tire, gas will be saved.Reward: See it implemented
