Mom has several times gone into her angry spin in a parking lot. She decides she is exiting the car and the only way to keep her in is to GRAB and hold on tight...she opens the door and throws her legs out. The simple thing to do would be to put her in the back seat with the child locks EXCEPT she is 6 feet tall and her legs will not fit in our Camry. Has anyone seen a gadget to attach to the seatbelt to secure it once buckled? She is so fast and can unbuckle and flip the lock before you know what is happening. Hoping someone else has worked this out or I will be inventing something quick.
