    Human eyes have incredible detail on where they are focused. A human will look to where the road is in the distance and see high detail of what is approaching from that exact position.

    A single side camera has a wide view of the world, so all the pixels are spread over the entire scene. There is no way to focus in on just where the road in the distance is. Keep in mind the road in the distance will appear in different parts of the image, depending on curvature of the road and elevation changes. i.e. it might appear high up to the Tesla if the road is coming from a hill.

    This is why you need incredible detail from the sensor, because you first need to determine where the road goes in the distance, and then focus in on that particular area for processing.

    Using low resolution images to try and determine objects at distance is subject to significant corner cases. For instance cars that are a similar colour to the road may appear to be just the road when sampled at low resolutions.

    Very common to have a 70mph speed limit (so many cars travelling >75) and uncontrolled cross or merges here in the UK. Hope FSD hardware has not been spec'd to work only on perfect US roads.

    A common set of intersections on UK roads. A27 (70mph limit) Arundel to Fontwell in West Sussex.

    I take it you've never been here? haha. Our roads are pretty far from perfect and uncontrolled crossings on high speed roads are very common.
