That example is how it should be.
Problem is that there are certain places and situations where the "right way" is less effective and need to be done differently.
Example: IF the yellow car turning left into the median has its own turn lane, then in that case, each car should stay left of the other oncoming car in the median....red car tuns in front of yellow car staying left. Otherwise it would be a complete cluster since there is a backup of turn lane vehicles for the red car to get through. Downside, large vehicles block the line of sight. It's kind of a problem no matter how you turn.
Are you saying in the situation where the turn lane goes all the way through the media? I'm not talking about that. I'm talking about your run of the mill medians like in the picture. That's 90% of the medians where I live. I believe I know what you're talking about though.
Lots of them around here.
Even the simple median cut through you talk about....there might be 5-8 cars trying to turn, so the whole keep to the right thing doesn't work out well. On your pictue, imagine 4-5 cars behind the red car and also behind the yellow car, each wanting to turn left...no turn lane, but just like you have there.
What works best then? I say keeping to the left works better than doing it the "right way". Sometimes, it better to deal with poor visibility and stay to the left...especially at a busy area where lots of turns through the median are happening in both directions. Not the official right way, but works in limited instances. Trouble is, it is up to each driver to figure it out and most drivers are dumb as a box of hammers it seems.
