There are a number of plastics that use soy in their composition; so, yes. I saw a video recently where hikers at a remote Montana trailhead leave the hoods of their vehicles open because much of the wiring has soy-containing insulation, which local rodents enjoy chewing on. If you leave the hood open, they feel exposed and won’t hang out for days, chewing up your wiring harnesses and leaving you stranded 150 miles from nowhere.
