... Characteristics of New Technologies II-31 Mode split could shift away from large transit vehicles toward smaller AVs, especially for people who have been dependent on transit because they are not allowed to drive. If the reduced labor costs of AVs result in lower per-trip costs, people may be willing to make more trips, which will increase travel demand.

From page 87...
... Characteristics of New Technologies II-33 No regulations currently require close vehicle following distances for CAVs, so the greater capacities would only occur if manufacturers and/or vehicle operators voluntarily selected closer car following distances for their CV-equipped AVs. Some states, such as Florida, do specify minimum following distance requirements: Florida currently requires a minimum 300-ft following distance for commercial trucks.
From page 88...
... II-34 Foreseeing the Impact of Transformational Technologies on Land Use and Transportation savings also would come from the fuel savings associated with truck platooning, wherein one or more AV trucks closely draft a lead truck. These cost savings could attract longer haul freight to CAV trucks and away from alternative modes like rail.
