Welcome to the forum and to Mitisubishi! The lack of this basic safety feature is a poor oversight, but hopefully one that can be addressed with software. There are plenty of other lock options under the vehicle settings.
Our only hope is that safety regulators take a more globalized approach where safety standards are the same regardless where you're located.Mitsubishi are not aware of how important is the feature that the doors are locked automatically after the car starts moving!!!!!!!
It is more and more important as time goes by.
The fact that Mitsubishi never had it before is not an answer! Please apply this feature, and the sooner the better!!!!!
