Have you ever seen or played the game frogger? It's where you are trying to get the frog to jump across lanes of traffic and not get smashed. That is what it is like when you are a pedestrian trying to cross the road here, whether one lane or six lanes of traffic.
It is a complete dichotomy to experience how slow and sauntering the Costa Ricans walk and then when they get behind a wheel of a car - it is like a bat out of hell! They criss-cross in the road, run through red lights, honk at everyone and everything. Signal lights and stop signs are only suggestions here. The cars are honking to go when the light is just about to turn green. When the light turns green and you're not moving - honk, honk, honk!!!!
If you are a pedestrian - watch your step in every direction. The sidewalks are narrow and uneven. Sometimes there is no sidewalk - just the street with no shoulder. If you want to cross the street, you do NOT have the right of way. Look left, look right, look left and right again and again and again. Then RUN!!! Sometimes traffic is stopped on one side and you can cross to the middle of the street. No island, no protection. Just standing on the double yellow line as cars are whizzing past. As soon as there is a break - RUN!! There are very few cross walks even in the big city. The game is to survive to the other side and not get squashed like a frog.
