I rode backwards for the first year or so of my life. I had terrible motion sickness in the car until my early teens. Then, I suddenly grew out of it. I haven’t had a problem since, and I never have had a problem with roller coasters.

I think all this chatter about how children are positioned in an automobile is quite interesting. My children rode in the front seat of the car, as did most children born before 1970, more often than not even just laying on the front seat so we could see them and talk to them while we were driving. If their father was driving, I held them on my lap. Seems like everybody did just fine.
