@s_h_ea I disagree that it's not about culture! The roads were constructed in a way to safely support bike transportation by virtue of being roads, and the laws support this. Cars driving too fast, too close, or otherwise irresponsibly is a cultural rift.
@s_h_ea One could make the same argument that drivers simply take a faster road like I-70 (where cyclists are not allowed!) if they wish to get around quicker. It's totally cultural.
