Transportation Secretary Anthony Foxx says such systems are
'just the beginning of a revolution in roadway safety.' But they could take
many years to show up in cars.
Cars of the future will know when they're about to get hit —
and how to speak up about it.
U.S. auto safety regulators on Monday took the first steps
toward mandating that automakers build cars that talk to one another. They
would speak in short-range radio signals, trading messages that would prevent
accidents on a broad scale, according to the Transportation Department.
