I know that. It's just that theory and practice aren't perfectly aligned. Normally, the emergency call should go to the responsible rescue coordination center (RCC). They usually know their area well. I worked in an RCC for the fire department and rescue services for over 10 years. They have trained staff who know how a qualified emergency call works. In the best case scenario, eCall connects to the responsible RCC and transmits the coordinates. That takes care of an important part. The RCC knows where the emergency is. The system also transmits the number of people in the car – this information is determined based on the seat belts, i.e., anyone who is not wearing a seat belt is not counted.
However, this is not enough. The dispatcher at the RCC can establish voice contact, as not everyone is responsive in every emergency. Things become difficult if people leave the vehicle after the eCall system has been triggered. In this case, voice communication via the hands-free system is of little use. I don't know whether further data would be useful for police investigations, but I consider this unlikely, as a system similar to an aircraft black box has been in development for some time. However, the technical possibilities would exist, and some motor insurance companies would like to have access to the data. According to the German automobile club ADAC, eCall currently transmits the following information:
- Time of the accident
- Type of activation: manual or automatic
- The 17-digit vehicle identification number (VIN)
- Drive type (e.g., gasoline, diesel, gas, electric) and vehicle class
- Vehicle position
- The last two vehicle positions (latitude and longitude differences from the current vehicle position)
- Direction of travel of the vehicle
- Number of occupants (if seat belts are fastened)
- Optional additional data (not specified in detail; may include, for example, an (IP) address from which further relevant data or functions can be accessed)
However, some eCall systems now connect to the vehicle manufacturer, which has set up a call center for this purpose — but these call centers do not have trained personnel like the RCCs, nor can they deploy rescue equipment. This means that an emergency call from the eCall system to the manufacturer can be very time-consuming. And time is a precious commodity in an emergency. In other words, eCall only makes sense if it connects to the responsible RCC via the European emergency number 112. I don't know how INEOS has solved this.
Incidentally, eCall should only be used manually for medical emergencies. Technical problems with the vehicle should
not be reported via eCall.
Of course, I can only write about Europe and Germany in particular; everything else is beyond my knowledge.
