<human>:  How does the new technology called ‘platooning’ work?
<bot>: Platooning is a technology that allows cars to drive in a tight formation, so that they can travel more efficiently and reduce the risk of accidents. It works by having a lead car that is responsible for maintaining a safe distance from the other cars in the platoon. The lead car is also responsible for communicating with the other cars in the platoon, so that they can adjust their speed and position to maintain the safe distance.
