aibu unreasonable to expect drivers on M3 and M25 (my usual routes) to have both rear and front lights turned on on their cars? So many times I have seen cars in the middle lane with no rear lights, almost invisible in the rain and spray, go to overtake them whilst swearing to myself, then in my mirror see that they have FRONT headlights on. How does that work? Why would you choose not be seen from the BACK?
