I haven't had to drive at night for a few months, but yesterday had to take OH for a hospital appointment and it was dark when we came out. The route home involves an A road, unlit and without cats eyes (we live in Spain), followed by a motorway, also unlit and the only cats eyes at junctions, and on leaving the motorway having to choose between a very narrow, windy uphill and down dale C road or three times the distance on an unlit A road. OH voted for avoiding the C road as there are stretches with a drop on one side... The motorway is the easiest part as the central reservation has bushes planted between the barriers so oncoming traffic lights are not a nuisance and cars coming from behind are easily able to overtake and get away from me as I pootle along at 100 kph. The A road stretches I find very difficult as there are few chances for overtaking, I stick to the speed limit of 80, and cars behind me get right up my backside with their lights on full beam. I find this much more troublesome than oncoming headlights as with those I can concentrate on keeping the car the correct distance from the line at the side of the road and not look directly at them. Are the night driving clip ons really that effective? I definitely need something, because OH's sight is too bad for him to drive, so it is down to me when we have to go out in the dark.
