Grip-It is a thin rubberized mesh that I purchase in 5 ft rolls (1 ft wide) at the Family Dollar and Dollar General stores for $1 a roll. It is supposed to be a shelf/drawer liner. If you put a cup or a fork on it, it won't slide.
Cut an 18" strip and put in on your passenger seat. Your passenger will not slide under rapid accelaration or quick stops or anything in between. They will find it a much more comfortable ride; I guarantee it.
It is also very good to put under your tank bag. My non-magnetized bag will stay on without any straps if I ride at all conservatively. And it protects the tank against scratching.
It is available in black, but you may have to try around a few stores to find that color.
