I live in California. I am a pedestrian. I have so many near-misses every week from people trying to make a right-turn, turning too fast, etc.
The drivers here are out of their minds. I see people break standard traffic laws all the damn time. If the speed limit is listed as 40, you bet your asses that the speed of traffic is at least 5–10 miles higher. That’s just how people do it here.
I don’t trust drivers. I am always on the alert when I am a passenger. I’m not generally a backseat driver, but I get scared.
So the 70–70 thing on opposite sides of the road: yeah it’s freaky, but so is just about everything involved with driving in Southern California.
