Does not only apply to Spain!!!!

If anything I'd say it was more applicable to UK where road rage can be a virtual daily occurrence with too many drivers driving in a state of barely controlled anger, something rarely seen in Spain.

I would also say in the UK the standard of driving has fallen in many areas of driving. It used to be very rare for anyone to undertake on dual carriageways or motorways, it seems to now be quite common practice. Failing to indicate something I find frustrating in Spain is also becoming more common in the UK. Density of traffic generally is much higher in much of the UK, outside of major towns and cities in Spain many roads are quite low for density of traffic compared with comparable roads in UK. Before moving to Spain full time 4 1/2 years ago I used to drive fairly high milage in the UK I often wondered if the change in things like undertaking etc was down to increase in foreign drivers rather than just decrease in driving skills or manners, I find undertaking very common practice in Europe. I find generally driving in Spain to be a more pleasant and less stressful than driving in UK most of the time. Cities in Spain I find quite stressful especially likes of Malaga City also in such circumstances I find spanish drivers to be very impatient probably due to them knowing the area road layout etc. As for roundabouts here yes different but generally I don't find them too difficult to negotiate so long as one ensures to bear in mind any vehicle to your right does not have to give way to you and usually will not do so, so if in a centre lane on a roundabout I ensure I indicate and get into the right hand lane in plenty of time. Some roundabouts with multiple exits in busy areas of Spain can be quite daunting.

Is it a nationwide issue with considerable amounts of people unable to cope with proper indicator use or more of a regional thing? Seems like there are four categories of drivers:

- those who do not use indicators at all. I agree with your point about BMW, Mercedes and Audi users being suspect of actually not having indicators installed in their vehicles.
- those who use them and then forget to turn them off, sometimes driving for a few kms like this (cannot hear the constant clicking, cannot see the constant blinking?)
- those who believe that you must signal left when changing lanes to the right and vice versa (also showing the right turn signal when actually continuing left on the outer lane of a roundabout)
- the minority that knows how to use (and actually uses) the car's indicators properly

Oh, and there's the tailgaters too, who think you will actually move over if they attempt a docking maneuver to connect their bumper to yours. Absolutely love educating those clowns that nothing could be further from the truth.

This is not exactly a roundabout issue but more of a tricky intersection question, but to put a long story short there are two lanes that then branch off hard right, slight right and slight left along with the flow.

The problem is that both lanes are allowed to go left... which then turns into a 3-lane road. There are no lines showing which lane goes where, so it becomes a bit of a free-for-all as to who can enter the middle lane with right of way (the left and right are obviously no-brainers).

From which lane (left/right) do you have the right of way to go straight into the middle lane in such a situation?

If I can picture it right, you would follow the roundabout rule because according to the regulations, a roundabout is classed as just a junction and the left lane is for overtaking.
You say both lanes are allowed to go left but also there are no lines showing which lane goes where - so two lanes come to a junction where there are three exits and there are no markings in the junction?
It sounds like from the right lane you can take any exit. From the left lane you can only take the left exit unless you move to the right lane to take a right exit - and yes, I understand there may not be room to do that.
If in the left lane, if again I picture it correctly, you would have to exit to the left into the middle lane or left lane of the three lane road if there ended up being a vehicle in the right lane also using that exit.
Something like that anyway - but the rules do seem to state you must exit only from the right hand lane, so if in the left lane, turning left, are you really allowed to exit into the middle or the left lane of the three lane road?

Did any of that make sense?

When in Spin drive like a Spaniard, there is no point at all in complaining about how they do it!
