To open a front door manually, pull up the manual door release located in front of the window switches and push the door open.
To open a rear door manually, perform the following steps:
1. Remove the rubber mat on the bottom of the rear door's map pocket.
2. Pull back the flap of plastic trim (if equipped), then pull the mechanical release cable forward and push the rear door open.
No small child strapped into a car seat is going to operate any release mechanism and even an older child isn't going to figure out those directions, even if Grandma knows what to do and is screaming it through the glass at them.
It's a needless and dangerous risk created by ignorant engineers and approved by ignorant executives.
I'd give the Tesla engineers a pop-quiz tomorrow morning, disconnecting the batteries and stuffing them in the vehicles in the hot sun. I'm sure they'll figure it out.
* No small child strapped into a car seat is going to operate any release mechanism and even an older child isn’t going to figure out those directions, even if Grandma knows what to do and is screaming it through the glass at them.*
A child strapped into a car seat won’t be able to figure out how to unlock and open most any door on any vehicle. They are dependent upon the adult who put them in the car seat to take care of them. Our car presently prevents you from getting locked out when a key is in the car. A sensor could be embedded to keep lockouts from occurring when a child is in a car seat.
