Right click game on the steam library, click on properties, then on DLC and untick the bonus content, this fixed it for me. If you want the bonus content tick mark it again after it is finished with unpacking.
The cars in the game already look fascinating but I hope the game had some sort of flying car too, maybe something we which we can't control, just as a part of cutscene.
If possible get the next-gen console as the next-gen update will surely improve upon many things and the game can be played on new consoles by using backward compatibility.
