Truck platooning gaining momentum

Tailgating has taken on a new meaning in the 20th century and it is referred to as platooning. Developers of technology to allow platooning say that automation installed in trucks connected behind a lead vehicle require one fifth the reaction time than a human would need. This quicker reaction time allows for reduced following distances at high speeds which produce measurable benefits.
Platooning allows two or more vehicles in a convoy to link their automated driving systems which would allow the vehicles to drive at very close distances to one another (30ft!!!). Platooning technology uses a variety of systems to take control of a vehicle i.e., radar systems, dedicated short-range communication, vehicle-to-vehicle communications, vehicle braking and torque control, cameras, etc.
A lead vehicle dictates and controls the speed and braking of all connected vehicles. This extreme reduction in following distance when tested (under optimal conditions) reduced wind drag up to 15% and reduced fuel consumption from 2.8% to 9.7% and inherent CO2 emissions along with it.
Platooning is yet another phase in connected automated vehicle technology and statehouses across the country appear to be onboard. North Carolina, Alabama, Indiana, Kentucky, Mississippi, Oregon, Utah, Wisconsin, Ohio, Pennsylvania and Michigan have or are in the middle of revising requirements for minimum vehicle following distances to support platooning technology.
