No, because the bus is across an intersection before OP enters the road—the “road” in this case referring to the single stretch of the street between those two blocks.

In any event, you proved OP’s point here by pointing that 1) the bus was across the intersection when OP entered the road, and 2) that the bus had the room to let OP by prior to blocking him in.

As far as the bus having to back up, technically that would be the case. However, I actually think OP did the smart thing by backing up, because yes, by that point, it was safer for them to do so than the bus since the latter clearly had no intention of doing so. Having said that, OP doing the smart thing does NOT mean it wasn’t the buses fault to begin with.

Maybe it’s “completely obvious” to someone who has no common sense and should probably take driver’s ed again.
