Nonsense, peasant!
Our highly trained paper pushers have crunched the numbers and determined this will save approximately the noise threshold worth of lives over time. Our propaganda people have polished that up, shat it out into the public discourse and the public wants it.

There's 3.5 millions calls to 112 per year. Out of these, 1 million were not transferred further to the emergency services.
There's been 37.500 calls to 112 originating from the eCall system. About 28.000 of them were not redirected to the emergency service.
So, the eCall system helped in about 10.000 cases, and contributed 2.8% of the non-emergency calls to the 112.
