"Bosch sees a number of applications for IOTA in a world where vehicles are communicating and negotiate with one another autonomously. One example Mr. Dekel gave is platooning—that is, when autonomous cars group together closely on a highway to reduce friction and thus fuel consumption. Platooning is similar to how professional cyclists and also birds move information to improve aerodynamics. With IOTA, cars wanting to platoon and take advantage of fuel savings could make payments to the car upfront. "
