That's true of other cars, too. They're big, change direction slowly, and are covered in bright lights. Pedestrians are small, can (and do) change direction quickly, and often wear dark colors, even at night.

Cars are also much more predictable. They have lines that show where they're going, (usually) signal before changing direction, and (IME) are much more likely to obey red lights. I rarely see cars simply ignore a red light, but I see pedestrians do it all the time.
