In VLM's analogy, the bike lane is entirely separate from the regular road (he said "deconflicted"). What he's talking about there is an entirely separate bike path, not a "bike lane" that's a part of a regular road with different paint. They're also frequently called trails. It is possible for a semi-truck to drive on such a path, barely (they're usually 8 feet wide; these paths are driven on occasionally by service vehicles after all, to construct and repair the path), but they'd have to run over all the bollards, and any bridges wouldn't handle their weight. Otherwise, it's a fairly accurate analogy IMO. No, it's not a very good solution to the problem of traffic on the roads, but for a few jerks it might seem like a good shortcut. (This is similar to how amateur radio bands don't have very much spectral bandwidth.)
