Isn't this similar to other Tesla AP accidents where it's a standing vehicle/object that isn't detected because it isn't moving. Something to do with using radar?

Is this still an ongoing problem for Tesla or is this a one-off thing where maybe AP was on, maybe it wasn't and the driver is blaming the AP (that AP excuse came up in my linked article when it was just bad driving)?
