Many consumers, and even some journalists, believe that 5G is essential for autonomous driving. But OEMs know that they cannot expect full 5G
coverage on all roads, at least in the immediate future, so they are creating cars that have the sensors and computational power necessary to
enable autonomous driving in offline mode. For vehicle-to-vehicle and vehicle-to-infrastructure communication, both of which are essential to
autonomous driving, 4G connectivity or Wi-Fi protocols are currently sufficient.
