Sorry for not keeping you guys up to date.
At the moment, I haven't really been working on the engine at all. I have been concentrating my efforts on my freelance work and at the same time looking for a more permanent job here in Maine.
Eventually, I will get round to finishing it off, or at least releasing the source code. In fact, I may as well release the source of it anyway, as it would probably take me ages to make a decent release anyway.
Anyone interested in continuing work on the Driving Engine?
