Possible, but should not be relied upon. Even in cases where the driver knows that a handoff to manual control will occur, it takes a significant amount of time to mentally switch from being a passenger to being a driver. For cases where the AI knows it isn't performing well, such as heavy rain or snow, it makes sense to handoff. For anything that happens on shorter than a 10 second timeframe, the AI must be able to handle it, because the human cannot switch modes that quickly.
