Well, to be fair, I would probably be a bit surprised to see a car covered with LEDs, no matter what the LEDs were displaying.

given that they had a week of filming, and the ability to edit the resulting video, presenting the desired expressions would not be too difficult.

Assuming it's not actors, they were probably posing for their friends on the other side. Some of them are bound to be photogenic.

If you did it anywhere in East Asia, you'd have a line (or what passes for a line) of thousands of people waiting to pose.

In other news, people can be paid to appear surprised and delighted in a TV commercial. Ric Romero has more at 11.

I don't think the sarcasm is warranted. They could be actors, but they don't appear to be. The more likely explanation is that people think it's cool despite the low resolution.
