I must preface this by saying that drivers everywhere are little more than animals, at least most of them, at least as far as most cyclists are concerned. Spanish drivers have an annoying and probably lethal habit of watching the pedestrian signal when they are stopped at a light. When the pedestrian light flashes yellow drivers here take this as their signal to proceed through the intersection thus shaving at least one second, perhaps two off of their commute times.
This coupled with drivers running through yellow lights makes you wonder how there aren’t thousands and thousands of accidents every day. The problem is mostly for cyclists as drivers may be looking either to the right or the left at the pedestrian signal and not see you as you make your way across the zebra crossing. The police could easily remedy this situation but they don’t.
