I agree. The photo description for "Here you can see that a car drivers waiting for people cycling are never in the way of other people in cars" would not hold true in my area of a US. There would quickly be at least two additional cars waiting in the main lane.

Yeah, it's important to note that this design is specifically for local side streets that are only expected to get destination traffic. If it's a busier street, there would typically be a separate turning lane, i.e. a bigger buffer.
