You can emphasize the "exit" as strong as you want, but I'd bet that "at the roundabout, take the exit to the left" from "Rua Garcia de Orta" to "Rua da Estação Agronómica Nacional" will never get a broader acceptance Even if the roundabout were 1/3 of the size.
IMHO from some 10-15-20 meter diameter upwards there should be only numbered exits. Howgh.
That's why left/right/straight is only triggered on roundabouts with 2 to 4 connections (hence why Y entry/exit triangles should be avoided), and only when the angle between the nodes is 90º +-10 or 15. This means for us in Portugal that when the roundabout is a clear "new" construction over a perfectly aligned X crossing (cruzamento) or T junction (entroncamento), and the roundabout big sign clearly shows the 90º, they should say the keepleft/right/straight. Or in other words, when entering the roundabout you can clearly see the 1 to 3 exits at the right angles.
On some cases with 3 segments that are 120º, I use my own greasemonkey script to assure they are literally 120º and will not ever say any left/right/straight.
Cases like the one I sent (Marquês) have 5 segments (6 because of some complexity on the south side related to the red/intermitent yellow signs) so it will always say exit 1st..5nd.
Anyway I've sent that roundabout because it's a "learn how to drive at a roundabout". The lines on the street are drawn in spiral so people are (supposedly) forced to drive to the inner lane and only start leaving to the outer lane when it's time to exit the roundabout.
Every day I see near-accidents due to people driving at the outermost lane, straight through the exit to leaving on the next or even two exits away, and at the same time smart asses entering the roundabout over the left (outer) lane to then leave right on the first exit, which is a beautiful accident to see when they almost crash into each other.
