So the driver was waiting in stopped traffic long enough to use his phone, and was so unaware of his surroundings that it took a full minute for the driver to realize he was being recorded?

If the driver took that long to notice someone next to him, imagine what else gets missed. At the /very/ least, he's the inconsiderate lout making everyone behind him wait until he wakes up to the light having changed.
