BMW has used a much more elegant solution since long before the Toyota incidents. Their mats are held in place in all four locations by flush 90 degree turn retainers that lock in to matching slots beneath the carpet. Thus, if not used they are invisible, and when used they are flush, secure, and self-sealing.
