In Europe there is a huge tendency to switch from cars to public transportation. Parking space in the city has become really expensive. New roads are built narrower and narrower in favor of walk-ways and bike lanes and to slow the driving speed down. In Austria there is a decline of about 1% of car owners each year.

The US has enough space for gigantic parking lots and wide roads. They don't have the same problems as in Europe. That's a huge difference that you are missing there.

I am looking forward to it. Don't get me wrong, I think the stuff you did there is impressive and I can't imaging where it gets when you have a proper source code with people contributing.

I would start with putting header guards in the files and remove the f_xxxx_ from your file (e.g. advanced-renamer can do that for you). Another suggestion would be to put everything the .exe needs into the "bin"-folder, currently your .exe loads some shader from your "src"-folder (or I did something wrong). I would also make a "third-party" folder in "src" and put all third-party stuff in there (also the LodePNG, zlib and bullet stuff in your main.cpp).
