You'd be hard-pressed to find a working passenger side seat belt in the front seat, much less the back seat, of a cab in Shanghai. This can be exceptionally disconcerting for those recently arrived in the city, especially after observing how people drive here. But never fear! After listening to today's intermediate lesson, you'll be well-equipped to request that the driver dredge up the seat belts that have been hidden away.
