> All cars in Europe must be connected to the internet at all times by law, to determine their location

The source you link very explicitly contradicts that:

> Your eCall system is only activated if your vehicle is involved in a serious accident. The rest of the time the system remains inactive. This means that when you are simply driving your vehicle, no tracking (registering your car's position or monitoring your driving) or transmission of data takes place.

(Also not in Europe but in the EU, there's a difference)

how does it determine "serious accident"?

I'll try to dig up the criteria someday, if they're written down, but I imagine that "anything that triggered airbag inflation" is a good approximation.
