| Free parking 
I hate getting parking tickets, so I sat down and thought of a way to get around it.When the parking wardens come round, they mark the front tyre closest to the curb with a chalk mark. On their next round, if the chalk mark is still there then they dish out a ticket. A modified automatic fragance dispenser that are used restrooms can be used to solve this problem. Instead of frangrance, it dispenses a black liquid (or similar) on to the top of the front tyre. When you park at a time limited park, you flick a switch and every 30 minutes or so the unit would fire and the chalk mark would be erased.The result is free parking.Reward: none, nadda, nothing

| Train Cars
It seams obvious that the most serious traffic accidents happen at the highest speeds. The idea set forth in this post can be modified for town driving, with increased technology, but I figure I will list what can happen “today” on the highways and freeways.I have commuted for many years in bumper to bumper traffic. Usually 1.5-2 hours a day. I often wondered if there is an apparatus that can be connected to the back and front frames of cars so that they can connect and disconnect like a train.The basic idea is that you would save fuel and traffic accidents by having every third car running at a much higher gear, at a much lower RPM, and the other cars would essentially be “off” or in neutral. All the breaks would be matched together through the hardwired connection that allows the cars to connect and disengage. This would mean it would have to be 3 lane highways, one lane (far left lane in North America) that would be at 150km/hour, then a middle lane to slip stream down/up, then an exit lane. Drivers would enter their destination into a telecommunications computer in the car, pull into “slip stream up” then the car would send out a signal detecting the “group” it would join (if traffic wasn’t bumper to bumper, otherwise a break in the group would allow for automated connection). The user then would get a signal for an “auto engage”, and the car would pull into the fastest lane, and connect to the other cars.0 distance between cars, allowing for more traffic on the roads, and increased speeds because all breaks work in unison. The strongest engines are noted and used, and the drivers get an automated deposit in their account for added gas / wear and tear costs. Big trucks, most can do this, the ones that cannot get up to speed are designated onto a different route of 80-90km/hr – and the money saved from accidents and environmental costs of running the cars is used to offset “side road” improvements to allow for this. Either you can use the technology that is being developed today (I have seen shows that talk about magnetic strips being used, but this does not allow for combined breaking nor lower gas consumption) so single cars can be to control the lead cars, or hire professional drivers to drive every day and to report any misuses, abuses, or problems on the road. The inbetween cars can lay back, relax or read on the way to school/work. A warning comes on before engaging and disengaging to notify drivers.Reward: Recognition, and the ability to read on the way to school/work when this is created!
