40. Perturbations continued. Suppose for convenience in Problem (6.15.39) that the displacements have a continuous distribution function and finite mean, and that d = 1.

Let LR be the number of points formerly on your left that are now on your right, and R₁ the number of points formerly on your right that are now on your left. Show that E(LR) = E(R₁) if and only if a = μ where is the mean displacement of a particle. Deduce that if cars enter the start of a long road at the instants of a Poisson process, having independent identically distributed velocities, then, if you travel at the average speed, in the long run the rate at which you are overtaken by other cars equals the rate at which you overtake other cars.

40. Perturbations continued. Suppose for convenience in Problem (6.15.39) that the displacements
have a continuous distribution function and finite mean, and that d = 1. Suppose also that you are
at the origin originally, and you move to a in the perturbed process. Let LR be the number of points
formerly on your left that are now on your right, and R₁ the number of points formerly on your right
that are now on your left. Show that E(LR) = E(RL) if and only if a = μ where is the mean
displacement of a particle.
Deduce that if cars enter the start of a long road at the instants of a Poisson process, having
independent identically distributed velocities, then, if you travel at the average speed, in the long run
the rate at which you are overtaken by other cars equals the rate at which you overtake other cars.
