Transmitting high-quality signals with very little interference makes it possible to incorporate V2X into various types of Advanced Driving Assistance System (ADAS) applications, such as forward collision warning and lane keep assistance. The R-Car W2R also conforms to the IEEE 802.11p communication standard
One nice side benefit with this package is that you can run infotainment on the companion processor and save money while planning for the future ADAS applications like V2X. How did Tesla offer OTA hards-free steering? They put the hardware in the car and activate advanced software later!
