Nobody said he did. He said the RIGHT lane was a TURN LANE. Which means the lane to the left of it could count on the people TURNING, not going straight.
WTF, YOU made the comment:
"If the right lane goes straight"
You might as well say, "if the people on the opposite side of the road cross the median..."
Yep. Which is why "If the right lane goes straight" doesn't make sense. We've already established that the right lane does NOT go straight, because it's a turn lane.
