Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may act as a leader vehicle for a set of UEs operating in a platooning mode. The first UE may adjust the beam direction of messages transmitted to the set of UEs based on a direction sensing device (e.g., an integrated gyroscope or a global positioning system (GPS) ). For example, when the first UE determines that a change in direction has occurred, the first UE may adjust the direction of the beam such that the beam points in the direction of a second UE in the set of UEs, rather than directly behind the first UE.After a duration (e.g., after the second UE reaches the location where the first UE changed direction), the first UE may re-adjust the beam direction to point directly behind the first UE.
