Absolutely! That's an interesting point about stopping distances being further back. That could make a difference maybe ? Although if a driver was that distracted they would probably go through that as well.I agree with you and 100% when the green man flashes it indicates it is safe to cross.
It's like a red light it 100% means you should stop.
One caveat for me is that when dealing with drivers you are always dealing with adults ,either licenced or unlicensed drivers.
With pedestrians it can be any age ,many people when kids get to a certain age of responsibility will allow their kids walk home from school alone or in a group or with a friend.
That's my reason for questioning the placement of crossings . A child will see the green and trust it and this should always be the case but authorities should have cognisanse of potential dangers and if they can help alleviate or lessen potential accidents happening then why not do it.
This also goes for stopping distances at crossings it should be further back from crossings same as parking close to crossings.
As you say ,careless driving ,phone use ,distraction ,lack of road awareness is rife and people need to cop themselves on behind the wheel .
I'm not convinced anything can be done except reiterate about keeping your eyes and mind on the road.
