Well in the mountains or in places where the brakes are used very often, the brakes get very hot causing the brakes to fail. Well how about if a rim was designed in a spiral form to "pull" the air toward the inner rim (where the brakes are located) and would constantly keep the brakes cool.

I thought that it might be a good idea that all emergency vehicles (police/fire/ambulance) should be fitted with an encrypted transmitter that mutes audio devices in surrounding cars when close. So receiving triggers are built into car audio devices and personal ones such as iPODs that mute when emergency services are close. For example if a police chase is taking place nearby and person on a push bike for example is being deafened by their personal audio device it gets muted so they hear...

Just like a mini cooper, but you take all normal or oversized vehicles and you shrink them down to mini cooper size and you keep the features as standard to the vehicle as possible (like the engine but smaller or any option or standard feature you would see in the full size vehicle.) A mini fire truck, a mini laborghini, a mini ferrari, a mini hummer, a mini stretch limo or any auto that exists or ever existed and make it to a smaller scale. Not only would they be cute, but more...

Sometimes the cause of an accident on the road is the lack of visibility, therefore if a car would have holographic stops and turning lights projected in the air on top of the car, it would be a lot easier to know what other drivers are doing.

I think it would be great if someone smart out there could build an alarm in the car that whenever your car is broken into or hit, not only does the alarm go on but your keys vibrate and make a sound letting the owner know that something has happend to their car. It's better to have this so that the owner could immediatly come out of whereever they are, like if they are shopping at the mall or something. Someone should make it because it's a Car Saver!

For areas in the world that suffer from frozen and icy roads. Tyres for cars are consumables, they wear out, and the rubber "dust" gets inbedded in and on the road. My idea is to make the rubber act as a de-icer for the roads. A chemical of some type would need to be added to the rubber to make the freezing temp of the water on the road increase. It would be constantly applied to the road through the wearing down of tyres.

One of my pet peeves in changing oil is that if you aren't careful, warm (if not hot) oil will run all over your hands. Further, almost always, I lose the bolt in the bottom of the oil bucket. Here's my idea. Cars come equipped with the oil pan bolt... the bolt is removed... BUT NOTHING COMES OUT YET! Why? Because there is another step. The oil changer then takes a wrench, after removing the bolt, and turns a nut (or for that matter, uses his hand to lift a lever, turn a knob,...

Signs at the roadside could eventually be done away with if a transmitter were to replace them. This could be picked up by a micro chip receiver built into cars. The information could be displayed or read out by a computerised voice. For instance you have just entered a 40 MPH zone. This could be encouraged by the friend of the earth groups, think of the tons of materials that could be done away with. Also when the signs needed updating this would be a simple download process from the...

On long trips, my active son is strapped into a car seat for many long hours. He would LOVE to stand up, but, of course, that is dangerous when driving. That and other things have made me do some thinking about baby seats. I have three ideas... First, when my son goes to sleep, the seat tilts so little, that he must literally go to sleep sitting up. It would be nice if the seat could really adjust so that he could be in a more prone position. Second, to strap my son in, I must go...

When we make a turn the car turns before we can actually see the portion of the road where the car has turned into. We can have movable headlights, which can turn based on how the steering wheel turns. So it would be like human eyes which would turn when a human turns into a corner.
