afaik... one of the most dangerous roads is a road in iraq (going to kuwait?). you need an armed escort to safely guide you and to repel any attack on your convoy.

another one is a highway in turkey (?). there are stories that on this 8-laner highway, the other vehicle on the opposite side would sometimes occupy ALL lanes when trying to outrun each other. btw, these are all trucks. hehe.

another is the alaska - canada road. you can only use it for certain days of the year and when usable, the drivers always have one hand on the door so that they can jump out anytime should their truck hit a soft spot in the road that can swallow the truck head.
