  In a perfect world, coordination and cooperation across distributed autonomous systems would be a trivial task. However, incomplete information, malicious actors and real-world conditions can provide challenges which bring the trust-worthiness of participants into question. In this work-in-progress paper, we propose the novel use of Distributed Ledger Technologies with a particular focus on IOTA to provide a trust overlay governing information interchange across autonomous vehicles. This paper outlines a number of scenarios where information interchange could provide useful data for decision making, defines how trust can be useful in this context, and provides use cases which call for evaluating the trustworthiness of the message. The paper also outlines the architecture of an IOTA-based private tangle integrated with vehicle simulation software which facilitates the evaluation of various scenarios.
