I agree that the adoption rate will be slower than the 3-5 years rate stated by the commenter above.<p>I do think, though, that of the major cities, many people would agree that Chicago is among the most resistant to changes in labor due to customer preferences, due to its unique political system.<p>That said, though, imagine how absurd it would have been 6 years ago to imagine the market share that the Chicago yellow cab companies are losing, to newcomers that didn&#x27;t even exist yet. I don&#x27;t think many people, especially cab companies and Chicago legislators, could have predicted it.<p>The swell of opposition in legislators against cheaper technological answers to current labor solutions is heroic- the question that remains is, &#x27;How long before consumer demand for the radically cheaper and&#x2F;or more efficient option makes the opposition moot?&#x27;.<p>The answer usually seems to be: &#x27;Sooner than everyone thinks.&#x27;
