They do take up a lot more space and as far as I can tell will create more accidents.

Here is one by my old high school in Crystal, MN. I just noticed it earlier this year on a map so it must have been built not long ago. It looks like they have removed a house on the right. I bet many accidents have happened there.

I think they could be safer. I posted links to videos of the few times where drivers went straight through them. Some were under the influence, some were police pursuits.

It's a mere fraction of the videos online of cars plowing through intersections that have traffic lights.

I think they need pillars or dragon's teeth to stop cars from going airborne over the top or driving straight through.
