Strange, there are no Driver Switch' setting in the LODs.iniYou just have to unpack the car's data file and you'll find the lods.ini file inside the data folder that's created.
Once you've made your changes, make sure you tick the box in the UI that says to 'use unpacked data if exists'. If you don't, you'll still be loading the original unedited data.acd file, not the unpacked folder with the changes you've made.
I tried adding the line, but it did not work.
