Boy, terrible idea, helicopter parent! You learn a lot about driving by sitting in the FRONT!
Actually, no, you learn by watching, and my teens noticed things better sitting in the passenger side back seat where they could see my feet, my hands, the dash and the road.

Actually age is very relevant. For example, even one-year-olds who are the size of two-year-olds still have the loose ligaments of one-year-olds.
"This best practice [of rear-facing until two] results from the need to support the young child's posterior torso, neck, head, and pelvis and to distribute crash forces over the entire body. Developmental considerations, including incomplete vertebral ossification, more horizontally oriented spinal facet joints, and excessive ligamentous laxity put young children at risk of head and spinal cord injury. Rear-facing CSSs address this risk by supporting the child's head and preventing the relatively large head from moving independently of the proportionately smaller neck."

Sorry, if my 12-18 mo. old is too large to fit in a rear-facing seat (i.e. his legs are smashed up against the back of the seat), then it's not safe to force him into it simply because of an age requirement. It's safer to put him in a seat that is adequate for his size and strap him in accordingly.
