A US Department of Transportation patent references the use of Hedera Hashgraph technology for digital road-user charging systems, suggesting potential future applications for per-mile vehicle charges as electric cars reduce fuel-tax revenue. The patent mentions Hashgraph settlement and consensus functions but does not confirm any current use or government adoption of Hedera's HBAR token. Analysts view this as a positive infrastructure signal for Hedera but caution that it is not an immediate revenue or token-demand event. The patent aligns with broader DOT strategies for automated and connected vehicles between 2026 and 2030, indicating possible large-scale digital tolling systems in the future.
