I don't quite understand. So now they have removed the auto lock feature, how will it be safer for motorists? What will be the difference between auto lock and manual lock upon collision?

Exactly, this is what I meant. At the current state in Klang Valley, the first thing I do once I enter my car is to lock my doors.

It will still be a challenge to open up my doors during emergencies if I can't open it from inside, isn't it?

So, do you mean that the auto locks are removed to discourage motorists from locking their doors?

Save cost. All new honda models also dont have it anymore since last year. B4 that can set autolock using Honda i-mid.
If not mistaken only KIA sell new models wt auto lock & auto unlock upon impact for all models.

The laws only said cannot have auto lock features wtout auto unlock upon impact (which usually brake base- auto lock).
