I would also contest this 'kids prefer a smooth ride' hypothesis. Obviously I'm basing this purely on my own two weirdos, but when given the choice between the smooth way home and the bumpy way home, the only time they opt for the smooth way is when they are poorly and / or emotionally distressed. The rest of the time they want me to smash as many roots, rocks, potholes and speedbumps as I possibly can.
