We have one or two here like that too. Usually it’s because they didn’t make them large enough diameter to get people’s attention.
My SE Michigan county has been installing more and more modern roundabouts. They’re greatr! Except… some obtuse people screw the whole rhythm up by confusing “yield” for “stop.”
Speaking of obtuse people and T intersections, there’s a T intersection right by my house. The north-south cross traffic has stop signs; the northbound traffic coming off the road that ends at the T has no stop sign. The reason is, that traffic crosses a very close railroad track, and so stopping traffic would present a danger. I nearly get T-boned no less than three times per month (when I’m home, that is). I’ve looked up the legal signage and petitioned the county road commission (it’s their road) for the appropriate DOT signals, but apparently every department in Michigan is broke.
It’s only because they invented the Stop Signin Michigan and we are quite nostalgic about our automotive pass here. Also, its hard engough to master the Michigan Left; even Texans have a hard time with it. 
We could discuss this in detail at the Dopefest in Milan (at Gfactor’s)on the 28th(?); you in? Spread the word.
Nah. You want nuts, I present the Australian Hook Turn.
I wish I could! That would be a blast. I’m still in Mexico at the moment and it’s looking like another month or two until we’re done.
Actually that’s pretty common in parts of Mexico, except it’s a drive-on-the-right country so it’s backwards compared to Australia.
When I moved to Long Island 25 years ago, Garden City used to have yield signs in some of its residential areas at ordinary 90° intersections. They changed them to stop signs not long after that.
