I'm sure it's been asked before, but I was wondering about how tall the Autobots and Decepticons should be in relation to one another, given their real-world alt modes. For example, Prime is a Freightliner FL-86 COE truck, which has a known size. Can we derive Prime's robot height based on the size of that truck? How about Bluestreak / Prowl from the Fairlady 280z? Starscream and the F-15? The Autobots from the first two or three toy series, Seekers, Battlechargers, Stunticons, Aerialbots, Protectobots, and Combaticons should be scalable, if any of them.
