You&#x27;re already wrong though.<p>How do you define &quot;cab&quot;? How do you define &quot;driverless&quot;? Do you mean from arbitrary point A to arbitrary point B, or can there be only pre-defined connections between hubs? Must they travel above ground on ordinary streets, or specialized streets? How many people can they hold? And how do you define &quot;driver&quot;? Under certain interpretations of your bet, the MTA system already satisfies those requirements.
