Hey thanks!
So turning. I don't want to claim to be an expert on tanks and I'm sure I've misunderstood a lot of intricacies. First of all you have to appreciate that, for several reasons, I intended this to be a WW2 game. So whilst neutral steer is very common (if not universal) amongst modern tanks, I don't believe it was wide spread amongst WW2-era tanks. And in the case of, say, the Tigers, neutral steer wasn't generally used as it was slow and damaged the suspension.
So since I was modelling WW2 armoured warfare, I deemed neutral steer to be ahistorical. Of course historical accuracy isn't a good excuse for clunky controls - even less so in a game jam.
