That is a very basic roundabout. I was expecting by "magic" that you would have to go round some part in reverse (clockwise for US left-hand driving). This is nothing compared to the original "magic" roundabout of Swindon, Wiltshire. This interchange might have been better off using a diverging diamond interchange layout [1]. While not a roundabout they are "magic" and we should use them more often. They just look co…
Hey all, I'm the author of this game. I didn't expect to see it on HN! I wrote it to add some fun to all the conversations happening in the local forums about this roundabout. They've been heated at times. And, yes, this roundabout is right next to the Kirkland Costco. I definitely agree with all the critiques of the gameplay - and I have about 100 more. I cut it down to the bare essentials to get it done while it's…

This thing is a nightmare of newly constructed, but with poor signage, rapid lane changes required at times, and "wait, which roundabout?"
Roundabouts are almost always a bad idea. Thank God they are mostly a European thing.
Roundabouts are almost always a good idea, assuming there is sufficient traffic. They keep traffic flowing faster, more predictably, and with fewer accidents.

Talking to my American colleagues, they're often perplexed by roundabouts and don't really understand how they fundamentally work. They're also incredibly stubborn when it comes to convincing them that it helps with traffic flow immensely versus a 4 way stop sign.
I almost like them, but my commute long ago involved one that revealed a frustrating pathological case. Constant traffic flow in one direction can make an entrance entirely unusable. It makes the average trip more efficient, but the worst case becomes dramatically worse.
Seems like a poorly designed roundabout then. You should just pull into the roundabout, right after the car already in the roundabout passes by. Something is wrong if one direction of traffic can block the flow from other directions.

I've been driving roundabouts for decades, and think they're great - they really help with traffic flow. I've never found them confusing. I had to drive this specific Kirkland roundabout the other day, and ended up missing my offramp and going in completely the wrong direction. It's the most confusing roundabout I've ever seen.

I too live nearby The lanes are quite narrow, and the outer curb is deceptive - there’s a 1” edge with a curved curb behind it making it look wider than it actually is. Scraping along that edge will push cars into the center of the road. There will be a lot of minor accidents here due to the road design. One other second order effect - people are getting used to roundabouts here now, but nearby are ‘traffic circles’…
traffic circles (w/ stop signs) are an abomination and should be removed

No, they just interrupt the flow of traffic by slowing it down. The classic pattern of side roads with less traffic yielding to incoming traffic on the main road carrying more traffic is the correct road layout that minimizes frustration and confusion. Roundabouts are the favorite tool of left-leaning, anti-car, vanilla soy latte-sipping urban planners.

Btw your 'classic pattern' of highly unbalanced traffic flows is specifically called out as a non-ideal candidate for a roundabout, maybe the urban planners get cow milk in their lattes after all.
