I thought it was just me getting older and worse eyesight that I can't see the lines when it rains. A lot of times I'm using the rain/fog/shoulder line to navigate especially when there are cars with lights coming toward me.

I've also noticed the really bright LED lighting they are using in street lights is making the glare significantly worse than the prior yellower street lighting. It used to be that you could tell when a car was coming the opposite way and dim your bright headlights but now it might just be a street light.
