Hello,
If the constant traffic irritates in TDU2, you can also deactivate him.
Go to:
X:\Program Files (x86)\Atari\TDU2\Euro\Bnk\islands\hawai\vehicules
and rename the "traffic" folder in "1_traffic"
do the same in:
C:\Program Files (x86)\Atari\TDU2\Euro\Bnk\islands\ibiza\vehicules
Now, the traffic is deactivated!
