What confuses me on roundabouts is the intended speed. Some are very tight and requires slowing down to 15mph and others can handle faster speeds. Rarely is the intended speed marked. A new roundabout in Brevard, NC has a very tight turning radius. There is a sign warning drivers in the outer lane to watch out for tractor trailers who will have to take both lanes to navigate the circle.

Yes, some residential ones are absurd. This one would've been better as a 4-way stop because there's no way to see traffic from all other sides due to the angles and obstructions. https://maps.app.goo.gl/GWoqaxNfVanXLymp6 https://maps.app.goo.gl/GWoqaxNfVanXLymp6 One went in here where people normally drive 60 mph: https://maps.app.goo.gl/Ugnm36mkeHs2zpu7A https://maps.app.goo.gl/Ugnm36mkeHs2zpu7A On Clark straight through, I would look for approaching traffic from either side or ahead and would cut across the hatched area, mostly maintaining speed. It's honestly better than stop signs or stop lights.

  The first one is totally fine. When you're entering the traffic you're driving at about 15-20mph due to the sharp curve forcing you to, so there is plenty of time to look for traffic already on the roundabout coming from your left. With the exception of the signage, I'd say this is a textbook example of a roundabout done well. The second one is a bit of a mess. The fact that it is physically possible to take them at 60mph means they screwed up the design. They should've used something like slightly raised cobblestone for the hatched area, and they should've used a raised shoulder at the entrance/exit. This roundabout looks like it was designed by someone who has only ever seen it in a textbook, and never actually driven on one.
