I second the narrow B roads in Wales. Very scary.North Wales, UK:
• Sheep are stupid, they don’t care about cars or horns.
• Narrow doesn’t come close to describing secondary roads (country lanes?).
I drove myself, but very cautiously.
Guayaquil, Ecuador:
• Lane markings are considered suggestions - 3 marked lanes, 5 (sometimes 6) cars filling the available space.
• The nanosecond a traffic signal turns green, cars as far as 10 back start honking.
I left driving to the locals.
I sort of shoulder check depending on what I'm doing. For the most part my vehicle yells at me if I even think about changing lanes into someone. But there's a catch. I have to signal first. If I start signalling and there is someone who has sneaked up into the blind spot it beeps at me.
I even get beeped at as I merge and if the signal lever is still on and there's a car in the inner lane it thinks I'm trying to change lanes into it.
