Further eCall info from FAQ...
What is the cost?
The basic pan-European eCall service, based on 112, is a public service which must be offered for free. Taking into account economies of scale, installation of the eCall in-vehicle system is estimated to cost much less than €100 per new car.
It is also expected that the eCall technology platform capabilities (i.e., positioning, processing and communication modules) could be exploited for additional services (e.g., advanced insurances schemes, stolen vehicles tracking etc).
Can the vehicle be tracked or hi-jacked?
The 112 eCall is a "dormant" system, i.e. the eCall in-vehicle system is only active when an accident occurs or if it is manually triggered. It is not traceable and when there is no emergency (its normal operational status) it is not subject to any constant tracking. As it is not permanently connected to mobile networks, hackers cannot take control of it.
What about privacy and data protection?
As the eCall in-vehicle system is only active when an accident occurs or if it is manually triggered, there is no privacy issue related to any tracking of the car. For liability reasons, the emergency call centres (PSAPs) will store the data related to the eCall for a determined period of time, in accordance with national regulations and with Directive 95/46/EC on the protection of individuals with regard to the processing of personal data and on the free movement of such data.
The road to eCall
The EU-wide, harmonised implementation of an interoperable eCall service has been on the agenda of the Commission since 2005 and is a priority action for the deployment of Intelligent Transport Systems. As an important road safety measure, the rollout of eCall is also a priority for the EU automotive sector, within the CARS 2020 action plan, presented by the Commission in November 2012.
In 2009 the Commission reported on the progress in introducing eCall and concluded that as the initial voluntary approach was insufficient, regulatory measures had to be considered. In July 2012 the European Parliament adopted a resolution which urged the Commission to submit a proposal to ensure the mandatory deployment of a public, 112-based eCall system by 2015 in all new type-approved cars and in all Member States.
