Some passengers had difficulty unfastening their seatbelts because they were unfamiliar with the mechanism (it differs from the type used in car seatbelts).
The practice was increasingly viewed as corrupt and a drag on unfastening the ties between private sector and state which prevent economic and political reforms.
With this, you could theoretically leave the seat belt latched at all times, and simply get in and out of the vehicle without having to unfasten the belt.
