Agreed. User interfaces should include very real human impulses. We're all somewhere on the OCD scale; repeated locking and testing should be accounted for.
Some do-- for example, Toyota's keyless system won't unlock the door again for a few seconds after locking, which gives you time to pull the handle to verify that it's locked.
For me it's not OCD so much as cognitive decline. I often just can't remember if I've already locked my car or not, but for some reason I can remember having tugged on the handle.
Many cars only have this on the front two doors. So feed your OCD by pulling back door handles?
Good advice -- I don't know of any cars that have this feature on the rear doors.
My car is a coupe. It doesn't have rear doors.
My car has this feature and I quickly learned that it only unlocks if you put all 4 fingers through the handle. So to check if it's locked I just give it a pull with 2 fingers and the unlock doesn't trigger.
