The new rules would have a big impact on car parts makers such as Germany's Robert Bosch [ROBG.UL] and Continental, and France's Valeo as they set out the mandatory safety features that every vehicle sold on the European market must have.

In a report published last month the Commission listed a number of technologies that were both feasible and cost-beneficial such as automated emergency braking, intelligent speed adaptation, alcohol interlock devices and cameras that replace rear-view mirrors.

These could be included in the upcoming review of its "General Safety Regulation" - expected next year - setting out the mandatory safety features cars must have. The cameras would merely be voluntary.

Alcohol interlock devices are breathalysers installed on a vehicle's dashboard. Before the engine can be started, the driver must breathe into the device.
