Maybe… after all, who routinely checks the backseat of a car when you get in it to move.
I was a school bus driver for three years.
Rule was to get up, walk back to the back door, looking at and under each seat. I always checked, hundreds and hundreds of times,
Once found a 7 year old sitting all alone in the last seat when I got the bus back to the yard. He’d fallen asleep.
Maybe I’m wrong because I’m assuming the car wouldn’t sit for 3 or 4 days in front of the station and I don’t know the lay of the land in Azusa or how busy this place was.
