Also, keeping your navigation display "north up" is much better than having one that will probably be laggy in a roundabout, confusing you on which exit to take.

If all else fails, look at the signage; I remember driving and a passenger not sure if the roundabout exit I was taking was correct, I said "Well there's a big sign there that says this way to our destination."

I've also seen a trio of 3 of them be adjusted (by changing lane markings and signage -- nothing of grand expense) in a way that was much more sensible and easier to follow than the original design.

It seems to me that a lot of the issues with them could be eliminated by having a bail-out path that is both safe and acceptable.

Logically, it seems like this ideally means providing the opportunity to simply go 'round again and do it over.

Or where that's not possible and there must be a lane with an irrevocable default exit, then: That exit should be low-cost and provide an opportunity nearby to safely stop and spend as much time as it takes to re-evaluate a second attempt

It should never dump a driver into an unexpected 9-mile-long Pavlovian clusterfuck.

The lanes are painted to "spiral" so that if you take the furthest left hand, by the time you get to the 3rd exit, it's the outermost lane.

Led to quite a bit of ribbing from the passengers so perhaps this is a PEBKAC after all.
