CAR TECH: Vehicle-to-vehicle chats will improve safety

It’s here. Cars can talk to each other. It is currently very limited, with the only vehicles on the road that can communicate with each other being the 2017 Cadillac CTS built since March 2017, but this is an important first step in improving safety for all drivers.
Vehicle-to-vehicle (V2V) communications are done using dedicated short-range communications (DSRC) and Global Positioning Sensors (GPS) that can send a thousand messages per second up to nearly 300 metres of distance between vehicles.
