If these cameras were set up to automatically shoot people with no concept of lane discipline...it's a pretty safe bet there would be far less tailgating.

Are tailgaters the main problem ? I dont think so, but are they an easier target ? Of course.

So the cameras wouldnt be tackling the cause of the problem.

Phone use is debatable. Under some circumstances I'd say the risks are low, other they are high. I see dozens of people on a daily basis using their phones whilst driving though. Most not even trying to hide it at all. Including some dummies who think holding the phone in front of their face on loudspeaker means it isnt to their ear so they arent on the phone lol

But Ive seen everyone from farmers right through to the police using their phones whilst driving. Some safely, some definitely not safely. A fixed site camera will never be able to distinguish
