A public service announcement on the dangers of texting while driving has been seen more than a million times on YouTube, but it’s also aroused cries that it’s too graphic to watch, writes CNET blogger Chris Matyszczyk. Together with filmmaker Peter Watkins-Hughes, the police department of Gwent, Wales, made the PSA, which shows a teenage girl driving some friends in her car. Engrossed in her texting, she is involved in a horrific accident. "You have seen far worse in movies and with far less good intent," Matyszczyk argues. "It can only go a small way to making teenagers and, frankly, half the alleged adults I’ve seen driving in California, consider the potential consequences of their self-involved habits. … There is surely nothing gratuitous about trying to save a life."
