Sometimes, when new technologies arrive, we get the language wrong. (How's that horseless carriage in your garage? Or your last trip on a flying machine?) /1 https://twitter.com/Waymo/status/1346870145021571073
We think that might be the case too with terms like "self-driving" or "self-driving car," which are sometimes used imprecisely to refer to otherwise helpful driver-assist technologies. That imprecision could lead to consumer confusion & safety risks. /2
Too, for a ccompany like Waymo that isn't a car company, "self-driving car" just doesn't work. For us, it's not the car that is driving, and it's certainly not the case that the car is "driverless." Rather, it's the Waymo Driver that's driving the car (or truck, or bus, etc.) /3
So we're going to do our best to be consistent and intentional with the language, and use terms like "fully autonomous" to describe technologies like the Waymo Driver that don't require a licensed human driver in the vehicle. More here
