Yes, I watch a number of urbanist channels on YouTube too. (I prefer City Nerd’s video more though.) Columbia does not have stroads.

> They have high speeds, the areas around them aren’t accessible via anything but a car, wide,highway sized lanes, long turn lanes, large signs meant to be seen from speeding cars

You’ve described a road or a highway - and in the video you linked to, those are the descriptors has had for roads and highways. It’s in the first like two minutes.

> constant traffic lights

Debatable for Columbia’s distances, and for the purpose of those lights primarily being for collectors intersections.

> and even destinations just off of them with massive parking lots between.

They don’t directly load onto the main parkways of Columbia, though. Nearly every one of the big box strip malls loads onto a side-road which then meets up with the parkways. Thus, that’s proper traffic hierarchy and not a stroad. If it was a stroad, all of the big boxes would load directly onto the parkways. See: your video.

Like really, the video you linked to has footage from undeniable stroads and nothing in and around Columbia looks like them. The closest is Town Center around the Mall, but that’s not even as clear cut as being “stroady.” Columbia could be called auto-oriented (although that does a slight disservice to the model for the villages being walkable), but it’s not stroady like Laurel, Silver Spring, College Park, Towson, etc.
