I "practice" medicine when I review my child's symptoms and treat with OTC solutions, but am not, nor do I advocate being a doctor. I "practice" accounting when I do my taxes and balance my checkbook, but am not a CPA. I also am allowed to design an addition to my house even though I am not a licensed engineer (and I can build it as long as I can get it approved by the licensed engineers at the county). So, I should be able to review crash data and make recommendations as long as it is made clear that I am not a licensed engineer.

I think its a "buyer beware" situation for the user of the recommendation to decide if they value a concerned citizen vs. a licensed engineer. And, it behooves the engineer to explain why their recommendation is better.

PS - I also see a lot of legal advice given on internet forums from people that aren't lawyers. Ohio code defines "practicing engineering", which it looks like reviewing and recommending do not qualify.
