Question: When they are driving to the pub, in the overcrowded car, Shaun's stepfather comments that the speed limit is "20 miles per hour." Shouldn't it be kilometers per hour. I'm American but the United Kingdom obviously uses the metric system.

Answer: The UK doesn't "obviously" use metric. We still uses miles for all road signs, but metric for most weights and measures. You buy pints in a pub, not a half litre. It's an odd mish-mash. Car speedometers have kph on them, but in a smaller font - mph is dominant.
