Search engines are free. Whether you own or hire a self-driving car, you&#x27;re going to have to pay for it, but all you really care about is whether it gets you from point A to point B. It&#x27;s quite binary--either it works or it doesn&#x27;t. There is objective and subjective factors the determine preferences towards search engines and phone. But if all driverless car tech works the same, then you&#x27;re not going to care which one you use as long as it&#x27;s the cheapest.
