Front doors lock and unlock

:
2010 CX-9 GT AWD
As you may know you can open front doors without unlock first.
However, i have a concern about that feature. I have tried open the door while it's locked and I'm driving, the door is still able to open. Back doors are working as normal. Do you think it dangers?
 
I've never had a car in whicht he doors could not be opened...UNLESS you had the child locks enabled. Why would you want to open your doors while you're driving down the road anyways? Just enable the child locks on the backseat.
