Still Trying to Figure This All Out
This^^^^The mystery here seems to be the weight on the seat (or perhaps Mom left the seat belt buckled). Perhaps the kid was kicking the seat cushion while lodged between the seat and pedals? Or Mom has a heavy purse and left in the seat, perhaps. Or moved the car seat to the driver's seat.
I buy the rest of the story and can certainly see how the toddler climbed through the open FWD, over the center console into the drivers footwell where it played against both the brake and accelerator while pulling down on the gear shifter. But not being the driver's seat with sufficient weight seems that should have prevented the car from moving. That part I cannot understand unless the seat sensor was not working as designed or she left a heavy object on the seat. Maybe I am missing something else but this has me stumped.
