You are absolutely correct–while this will probably be buried among all the other replies, I want to share the video essay by overzealots that confronts the liberal media’s propaganda/disinformation campaign surrounding the Cuban revolution.

Not the OP, but knowing someone who’s been through something similar I can answer a few of your questions. She had this surgery nearly two decades ago, so modern procedures may be completely different:

• Adipose tissue and skin from the belly was moved to the breast. The tissue was left completely intact, including nerves and blood vessels.
• A nipple was tattooed onto her skin, no tissue sculpting, etc.
• Since all the nerves and vascular system was intact, any sensation on her new ‘breast’ was still mapped to her belly.
• Her new breast was sculpted to be the same size and shape as the healthy one.
• Since her new breast was made with belly tissue, any weight gain/loss may be uneven compared to her other breast.

If it requires special training and awareness, it’s not a good solution for American traffic patterns.

I think the issue you’re pointing to is that some drivers aren’t good at driving, and that puts others at risk. If that’s the case, I agree; there are a lot of bad drivers on the road, but that’s a problem everywhere, not just in America. I’d say that overall American drivers are, excuse the pun, middle-of-the-road when it comes to safety. Addressing the claim that if something takes special training and awareness then it’s not a good solution: driving in itself requires special training and awareness. Every driver on the road is required to have taken a driving test and receive a state-issued license. But that doesn’t stop people from disregarding rules and breaking laws. Even great drivers will make mistakes, and sometimes those mistakes will have deadly consequences.

We cannot eliminate driver error without removing drivers, which will never happen in places with car-centric infrastructure and culture. What we can do is mitigate risks and reduce the severity of collisions when they inevitably occur. The data show that roundabouts are safer and more efficient than other forms of traffic control, and when collisions do happen, they happen at much lower speeds and oblique angles, which lowers the risk of injury and reduces cost of repairs.

The argument that roundabouts are bad because it means learning how to use them is an indictment against drivers, not roundabouts.

I’m with you on everything except roundabouts. For moderate traffic intersections, they are more efficient than stoplights and stop signs. Opposition to them seems largely confined to those who regard wide arcs and looking left for other traffic as unreasonable demands against their intellect.
