Welcome to the 7daystodie forum and be warned anything can happen here.
1. development of new ideas and restructure is not a waste of development... regardless if we like or dislike something (the game is not out of development yet and anything can be added or taken out).
2. "Nobody wants game turn into some Fallout based RPG"? betcha there are a lot of people here who may want just such a thing. it can be asked and you can see by the threads here that 50 different people will want 50 different styles/variations of the game.
3. Heads Up... things can change but MM said in one of his recent videos that the car is a place holder as the 4WD is a truck/SUV type vehicle not a car... (but i said things can change).
enjoy your stay.
