In real-world operations, which often require some degree of shared control between driver and automation, such moments can arise from human error or from automated systems that cannot anticipate rapidly changing conditions.
They are rare, but when they do occur the consequences can be serious. A car may handle a thousand gentle curves perfectly, but fail in a sharp curve taken a little too fast.
Current autonomous systems are not trained well enough to reliably handle these moments. From data…
