I failed on the dash radius just on the bit under my right knee as I thought it was in the exclusion zone. As a quick fix I glued some 13mm silicone hose under the vinyl which got it through and then was immediately un-glued and put back the way I'd intended. you can just see it bulging in this pic. I wish I could physically move my knees that high for it to actually be a safety issue
The rest of the under dash radius was ok because I'd planned it in around the guidance.
