Note 1: I decided that instead of a huge optimization update that would take a year I will make smaller content updates with some extra optimization attached to it. This way players don't have to wait for a year for the big optimization patch and get updates more frequently with some optimization and get new content in the game at the same time.
Note 2: New brakes and exhaust feature have been introduced to the game, therefore if you load a save file all vehicles will start with no brakes and no exhaust pipes. Brakes and exhaust pipes can be bought at car part shops, use the bus stops to get around and buy brakes before you start driving. Or drive very carefully.
