"Limited access" roads already exist. These are the places for unlimited speeds in autonomous vehicles. Everyplace else it should be assumed that cyclists and pedestrians are in the mix, and even if traffic signals for cars become obsolete, those cars will still have to enable bikes and pedestrians to move without joining the v2v network. You might be able to provide a safety advantage to cyclists and pedestrians carrying beacons, but you'll never be able to count on it, so city traffic will have to remain within speeds that keep un-instrumented pedestrians and cyclists safe.
