Siri/Alexa/GoogleAssist etc. work well in constrained situations (e.g. changing music, turning stuff on/off, pop culture quiz questions), they have trouble parsing more general/complex questions. Many researchers I've talked to believe the initial self-driving car deployments to the public will be have to be very constrained: fixed routes, possibly isolated self-driving car lanes, only allowed in clear/daytime conditions.
