So what is the signage on a typical roundabout in the US?

There would have to be typical roundabouts in the US before there could be typical signage for them. The handful of ones I've encountered have zero signage before you enter them. You just have to read the signs as you encounter them while going around. Which helps you get it right your second trip around.

In Texas they seem to be "semi-roundabouts." They go round, but you yield to the traffic on the left. And that's the only sign you have, a yield sign. We have both single lane and double lane "roundabouts" and you stay in the lane you enter into — so it's a completely different deal. More like an elaborate four way stop. It does actually work better than a traditoinal four way stop — unless people get confused. Sometimes they turn against traffic, which is always a little fun.

I'll have to disagree with you there We had the small roundabouts put in in my local area. It's a quiet residential area with a speed limit of 20mph but the problem is the roads are wide and some folk think it's fun to drive through at 70mph instead. We were originally going to have 4 way stop signs which would have been cheaper to install and allow more parking but these junctions are very rare in the UK and it was thought to be a little risky. The raised mini roundabouts force the cars to slow down. Obviously if folk just drove along at sensible speeds then there wouldn't be a need for any of it.

Speed bumps are bloody awful for ambulances. Or, more accurately, for ambulance patients.

True. It's a question of how you balance the increase in road safety to the entire community of enforced slow-downs by speed bumps against issues caused by them to a very small number of emergency response vehicles. These things are always a compromise. Where does the greater good lie?

And because they are flow-controlled by a yield-on-entry approach, they are especially poor on interchanges where there are unbalanced entries (e.g. smaller arterial roads crossing high-flow roads). See https://academics.utep.edu/Portals/1..._Rab_ver7a.pdf Also https://www.acsengineers.com.au/2016...raffic-lights/ It's led to the curious situation where the US is adding tons of roundabouts (in smaller cities and towns, and less busy parts of big cities) while the UK is seeing a boom in new signalled intersections (at busy intersections). https://www.theguardian.com/cities/2...abouts-way-out |

Things like OCR (computers being able to decipher printed words—or handwritten ones), speech recognition (“OK, Google!” or even the phone systems that say “If you wish to sign up for new services, say 'Yes'”), decision trees (how do Amazon, Netflix, or Kobo make recommendations based on your profile), motion planning (how does the Roomba decide where to go next?), are all considered forms of AI. What you're talking about is usually called “artificial consciousness”, and is even a higher bar than what's generally called “Strong AI,” itself a much different concept from simple AI and one that encompasses both artificial consciousness and artificial general intelligence. |

Amazon already does produce AI generated novels. Hence all those romance novels that are on Kindle Unlimited.

I hope you aren't saying the one about the billionaire biker boss who falls for his shapeshifting BBW secretary wasn't a novel straight from the author's soul!
