Your quoted text actually justifies Amelius&#x27; assertion: the functional category is the same, but the implementation differs, and the judgement (and the law) hinges on implementation.<p>All this means is that the definition of taximeter (as a single-purpose device) is now outdated. It&#x27;s actually a pretty bad example of the law adjusting to new technologies.<p>Just because we like the outcome doesn&#x27;t mean we have to like the way it happened.
