Making vehicles drive through a mesh

Welcome PiiderOss! Although I completely get your approach (honestly i would have done the exact same thing) - Your best bet is to match your road markings with decals to avoid the flickering. At some point, you have to force your workflow to TM… The amount of time tweeking, thinking about how to make it happen ends up less time if you can use the TM objects… Feel your pain… Good luck… Would love to see the end product!
