Sorry, but this mod is straigh dogsh1t,
cars behave in a really buggy way. They constantly slow down and speed up for no reason whatsoever. Also, the traffic just refuses to merge into the right lane. 500+ cars and not a single one in the right lane. Instead, they cause a bumper to bumper traffic jam in the left and middle lane, making swimming though traffic impossible.
The only reason this mod exists, is to bait people into buying the actual mod. The free one is incomplete and not at ALL worth your time!
