One often cited use case for vehicular networks are applications that relate to emergency vehicles. In addition to the traditional siren, they could use radio communication to warn other vehicles or to preempt traffic lights. Such an application can reduce accident risks during emergency response trips and also help save valuable time. We developed a comprehensive design of such an emergency vehicle warning system that makes full use of inter-vehicle communication but also encompasses roadside infrastructure like traffic lights. In our system, other vehicles are not simply warned of an approaching emergency vehicle; they also receive detailed route information. Based on this information, timely and appropriate reaction of other drivers is possible.
A prototype of our system has been implemented with the U2VAS VANET communications stack. This video shows tests in a traffic environment including emergency vehicles and traffic lights.

I would definately NOT wait half an hour either at the side of the road or to cross an intersection and I know I wouldn't be alone - there's a reason emergency vehicles have sirens and that is to give away their positions. So I don't see why this would be useful in any way since they are heared from far away? :)
