Drivers don't normally see me as I'm sat in my car. Mind I did have a woman approach me asking if I had just photoed her car, she was happy enough when I explained I was photoing the buses. Though drivers being abusive to me doesn't bother me, I just roll my eyes. If I get flipped off their prob get caught out in the end anyeay, especially if the management is enthusiast friendly and regularly look at the bus photo online.
