Mod installation problems

I installed some mods and they don't show up in the vehicle selection menu. However, they show up in the mod manager. All are listed as "ACTIVE". What did I do wrong?

 

i found what i was doing wrong which was doing the same problem as the original post had, you have to place the mods in documents/beamng.drive/mods as a zip folder now, can't just be a regular folder anymore it has to be a zip folder
