I think the issue is that people see the reckless driver and think "That guy deserved to be ticketed but I would never drive so recklessly while I'm texting on the road! I'm perfectly aware of everything and so I don't have to change my behavior going forward" while seeing people busted for holding a phone regardless of how they drove tells them that if they are seen texting on the road they'll get in trouble even though they are "flawless" drivers. a dash cam might see someone holding a cell phone to their face, but people texting or checking social media sites tend to keep their phones in their laps which is why police want the birds-eye view of a semi to spot them. Bikes have been used at intersections but with low held phones and high SUVs that wasn't always very effective.
