Answer: “talk” to each other
While it’s no K.I.T.T., the talking car from Knight Rider, Cadillac’s new CTS sedan isn’t too far off. Equipped with a vehicle-to-vehicle (V2V) communication system as a standard feature starting with interim-year 2017 cars already in production, the new models will be able to “talk” to each other on the road, according to a press release from the automaker.
Cars enabled with V2V can share information about road conditions with other connected cars up to 300 meters away, or about five cars away in normally flowing traffic. This will alert drivers of nearby vehicles to any possible hazards they may otherwise not see, such as slippery road conditions or a hard-braking car.
The system uses a combination of Dedicated Short-Range Communications (DSRC) and GPS to share data with other cars, and can handle up to 1,000 messages per second. Although the technology is currently limited in scope, available only on the Cadillac CTS, last year the National Highway Traffic Safety Administration proposed mandating V2V in all cars.
