Taking into consideration the lengths Belt-san went to have Shinnosuke become Drive (have him transferred to the special unit, give him Tridoron... which begs the question "Did nobody on that team find it weird this random detective got assigned to a unit nobody takes seriously and yet given a shiny new car for it?" but I'm not into the habit of overthinking my Sunday morning shows so heh), the guy probably does have something that makes him more special than the average human. We know pretty much nothing about Roidmudes for now, what if Shinnosuke was in fact one without knowing it? That could get really interesting later on.
