My sister is 10, and she and my parents insist that as long as she calls shotgun, then she can sit in the front seat, even though I m older and taller! Anyways, my mom said she d change the rule if I could present a well formed presentation on the subject. I m trying to work the safety angle, but all I can find is that people under 13 should sit in the back, which is fine with me cause I m older than that. The only problem is that the reason people under 13 should sit in the back is because of their size and my sister s 5 4 and 118 lbs. Any ideas to still work this angle??
