On some vehicles, people are VERY serious about what they're looking at and how they're looking (e.g. serious video/photographers, birders) and don't want kids mucking about "ruining" the drive. I was once on a drive with serious birders (me, I'd rather watch paint dry) and an all-too-happy to abide ranger. By the end of the stay, I was going mad over the differences between yellow-bellied whatever and the blue-billed flying thingy's various calls, colors, etc. Wanted to rip the birder book out of their hands and throw it in the dam.
