Good idea, Pork Pie and thank you.
I can't, at this time, move the car outside but I did take the canopy out in direct sunlight. If I point it at a dark object, like inside my garage, visibility goes to near zero. If I point it to a bright spot, visibility is very good. I reckon once the car is on the salt and pointed down track, all that white should help a great deal. I have a picture of Speed Demon from inside the car (see attached image) and if there was a visibility problem with all that polycarbonate, this car would have had it.
