There is no way a properly installed mat will interfere. Maybe if the right front of the mat was folded under the pedal but that shouldn't happen naturally.Looking at you picture I am wondering if the pedal was adjusted closer to the driver and pushed to the floor if it could catch the edge of the pedal on those raised ribs and the pedal would not return to neutral when you took your foot off?
Pedals adjusted all the way to the floor.
