Forests are an area ripe for illusion, because the trees, and the light showing through them can seem to indicate something which does not exist. One person might see it, another not.
However, if a person is concentrated on the road, and their driving, the effects can be lessened.
All kinds of visual processing issues in a forest. Usually darker, can create a kind of short-sightedness even in people with good vision. Less light around to bounce off objects so edge perception (where an object starts and finishes) is poorer. Visual field in a forest could play around with depth perception cues. Strobing effect of sunlight as others have mentioned.
Also, more blind bends, far more chance of an inappropriate speed, considering the 'only go as fast as the distance you can see to brake in' rule.
Good chance of greater speed differentials. A 'closed in' driving environment (structures/trees close to either side of the driver) increases the sensation of speed. Some will slow down more, some will be stimulated to drive like a WRC driver.
Also, less light on road, more likely to be wet/icy/. More chance of tighter bends? Off camber apexes caused by root growth?

A few years back, Graham Hill did a TV series in driving tips - (if anyone remembers it, it featured him driving a mile or so through traffic with a glass of water balanced on the bonnet of his car!!).
I drive to work with my apple on the passenger seat. If I find it rattling around the footwell I know I haven't been smooth enough!
