That's one of the reasons why the "Share the road" sign is being phased out in favor of the "bikes may use full lane sign".
The proper way to share a lane is in serial fashion, not parallel. This is because lanes are rarely wide enough for a car or truck to pass a cyclist with sufficient distance between the two while both remain within the lane itself.
In fact, many state laws that specify that cyclists must ride as far right as practicable actually have the substandard width lane exception (described above) to that requirement.
One day when I had reduced ride height due to a tire issue, a "traffic calming" device cracked my oil pan. That was just great for the environment. I leaked carcinogenic used oil all along the way, and then had to get the oil pan replaced. The creation of that new oil pan involved industrial activity that surely was not good for the environment.
Long ago, when I was working in western Tennessee, I noticed that, in that area, the painted bike lanes were almost always on arterial roads. I even found one that was on a stretch of controlled access highway. Asked a colleague who worked for TDOT about that, and it turns out that you could get extra federal money for roads with bike lanes. So of course, the counties would put the bike lanes on the roads that cost the most to maintain, not the ones that made sense for bicycles.
Outside of a few major cities, I suspect that's invariably how bike lanes are going to end up working in the US.
What you could get people on board behind, though, is traffic calming measures. Bill it as fighting back against the hordes of Waze drivers blasting through your neighborhood as a shortcut, and you might be able to get some political momentum behind it. That would then get you to roads that could support mixed traffic without half-assing it by painting cyclists into a thin ghetto full of potholes and broken glass.
And then pair it with movements to get some questions about how to share the road with bicyclists onto the written driving test, so that drivers at least know how to share the road with cyclists. Right now, nobody's telling them, so they genuinely don't know. Even here in Chicago, I've had surprisingly many water cooler conversations where I had to correct a complaining car commuter who thought that it was illegal for all these bikes to be in the road and that they're supposed to stay on the sidewalk.
