class_docstr: ConstantVelocityAgent implements an agent that navigates the scene at a fixed velocity.
  This agent will fail if asked to perform turns that are impossible are the desired speed.
  This includes lane changes. When a collision is detected, the constant velocity will stop,
  wait for a bit, and then start again.
