Should Left Turns Be Banned During Rush Hours???

Is this something to consider as other cities have adopted the no left turn policy at busy intersections.

It sure would be a pain if all you needed to do was make a couple of left hand turns to reduce your travel time to get to work if you’re running late?

Around 40% of all crashes happen at intersections, and over 60% of those crashes involve someone making a left. Half of them involve a serious injury, and one in five involve a fatality. So experts say banning left turns at busy intersections would save a lot of lives. Another reason to do it is they make intersections less efficient. Green arrows make left turns safer, but then everyone else at the intersection has to wait just so a few cars can turn left. There is  a movement  for more cities to make left turns illegal, at least during rush hour. It would save lives, and maybe, get you to work a little faster. Any thoughts??
