As a Spaniard, I had become reconciled with Madrid in the last years, I visit frequently it has really improved a lot. But now it's likely to become a dirty, congested den of corruption again, I don't think I will keep visiting it.

Note that the regression is still not implemented, so you can still go and enjoy it before they ruin it.

Are you not going to visit Madrid only because of views of its regional politicians or you were hoping the number of cars on the streets will be significantly reduced by time you get there? Just curious.

The PP aren’t even in power yet and when they are they won’t be able to implement it instantly. If you are in Spain at the moment this shouldn’t put you off.
