> Can you imagine being dumb enough to drive over the speed limit around a double parked SUV in a school zone? Can you imagine being dumb enough to think that exceeding a one size fits all number on a sign by As if 2mph would have fundamentally changed this. Pfft. A double parked car, in an area with chock full street parking (hence the double park) and "something" that's a magnet for pedestrians, and probably a bunc…
The default, with good visibility in ideal conditions, should be to not exceed the speed limit. In a school zone, when in a situation of low visibility, the car should likely be going significantly below the speed limit. So, it's not a case of 17mph vs 15mph, but more like 17mph vs 10mph or 5mph.
The car clearly failed to identify that this was a situation it needed to be going slower. The fact that it was going 17 instead of 15 is basically irrelevant here except as fodder for moral posturing. If the car is incapable of identifying those situations no amount of "muh magic number on sign" is going to fix it. You'll just have the same exact accident again in a 20 school zone.
