I thought the whole point was they get run over and are easy and cheap to replace.

But yeah the big jump was supposed to be temporary and it's now been the same for what 3 years?

That may have been the point but it doesn’t seem like a good longterm solution. Eventually you will end up spending more money on constantly replacing these things than just installing something sturdy that you may have to do upkeep on once a decade.

Additionally, the fact that they are so cheap and replaceable makes for very ineffective protection and traffic calming. I have watched people in all manner of vehicles simply run them over or even park right on top of them.

The flex posts are not rigid because busses and other long vehicles need to be able to run them over.

Buses shouldn't need to run them over. AFAIK, the only flexposts that are meant to be permanent are there for emergency vehicle access (which itself shouldn't be necessary, but BFD isn't a fan of smaller trucks in general).

I guess, if those pylons at R House were rigid, a lot of busses and trucks I've seen would be totalled.

Trucks and other buses in cities across the globe can navigate turns like that. Why can’t we?

First I should say that as long as the person in the opposite lane of the road I'm turning onto stops at their stop line, I have no trouble making the turns in my personal vehicle. To your question about busses, the right turn from 29th onto Remington has a corner radius ~5' and an effective turning radius, including the use of the southbound lane, at ~15.' Busses apparently need 21.5' or more inside turning radius, implying these intersections were designed for busses to drive over the pylons when turning. An interesting note is that at 15' radius and the minimum given side friction factor, I get 8.5mph as the design speed for that turn.
