Automotive communications

Hello,

I have an idea of making automotive communicates with each others by bluetooth.
the scenario is like mobiles. When you are on the road each car can discover its neighbor by bluetooth to get specific information. This information vary and depend on the usage of it.
the major advantage is to get information chain from all cars around you. For example, you get information about the speed of the first car in the queue by collecting this info from the car in front of you. It works like you ask the car in front to get this info from the car in front of it and so on.

Imagine if we do query like this in a long road, then we can know if we have traffic jam at the end of the road in real time. this will help find a different route if possible, also we can broadcast this info the traffic center in order to take action in early manner.

One of this information also is to get the id of the current driver. this is useful for traffic police. Also, will help know who is the driver and therefore we can get chain information on all the drivers on the road. This may introduce a new communication channels and also it can be adopted to find if we have buddy on our buddy list on the road.

We can also make audio calls to this buddy by allowing all bluetooth devices on each car to act as an audio gateway of each others, then we can a good communication center similar to GSM.
