OK.....Here are some pictures that show the All weather mats, over the carpeted mats, with much less distortion than your photo!
Answer this for me:
In all the pictures the mat is underneath the accelerator pedal, so how would that interfere with holding the pedal down for unintended acceleration? IT CAN'T!
The only way I could move the mat to 2" forward(for illustration), was to lift it up manually, because it was impossible to make this shift by sliding it, due to the deep dimples on the bottom of the mat! You'll still notice that even in the wrong position there is NO restriction of the accelerator pedal!
Even if I lifted the mat to be on top of the accelerator pedal, the pedals return spring will still be stronger then the weight of the mat.
All these, "what if" scenarios are really becoming quite ridiculous!
Mat's in Normal Position
Mat's in 2" Forward Position
