full auto is not practical unless by full auto you mean the driver can opt-in at any point with a clear protocol for doing so.<p>I think the mistake people are making is thinking the vehicle is just going to be like &#x27;welp, death imminent in 5 seconds, hairy pink skinned passenger, here ya go!  do somefink abooot it!&#x27;.<p>In reality the vehicle is going to be assessing potential risk and let the passenger know when they need to be more attentive, even to the point of simply refusing to operate without the passenger signaling their attentiveness in some manner.
