"We ensured that the vehicles equipped with 112 public eCall are not traceable and are not subject to constant tracking."
Uh huh.
"In fact, the device will upgrade the data constantly and keep the minimum information required to handle the emergency calls."
With my not-so-tinfoil hat on, I think this last bit should be more like: "In fact the device will have whatever half-assed security we decide to throw into it, and by the time the NSA and GCHQ (or even just a bored script kiddie) have finished with it it will be thoroughly pwned and they can then use it to track you, and should they be so inclined, modify the data and/or 'test' the functionality."
