A childhood belief about cars

When I was little, my family would frequently visit friends and relatives who lived on bumpy or gravel roads. I was still too small to be able to look out the window and see the road. Shortly before we'd approach pavement, my dad would reach down beside his seat and say, "Gee, I'm tired of these bumps. I'm going to push the road smoother button." Like magic, there'd suddenly be a smoother ride. I believed this for YEARS until one day we were stuck on a bumpy road for a long time and I begged my dad to push the button. He told me that he didn't feel like it, that he was enjoying the bumps. When we got home I told him I didn't believe him anymore. He said he'd prove it, and showed me the seat-adjusting handle, explaining that it was the button. I continued to believe him for at least another year.
