This is pretty cool as a trompe l'oiel, but it's just plain dangerous to put deceptive markings on a roadway.
The should have called the project "let's train our drivers to ignore raised obstacles on the road".

And now you'll get surprising behavior from random cars, and normal behavior otherwise, which is probably more dangerous than whatever speeding was occurring in the first place
But now someone's desire to have slow traffic is satisfied and they are no longer pestering the local government who is no longer pestering the highway department. That's mission accomplished as far as they care. Making the local transportation infrastructure not suck is not a metric they are evaluated by so all the second order effects are irrelevant.
If you're lucky the marker will have a snow plow accident in a couple months and it will never get replaced because everyone will realize it actually made things worse.
Also, it's worth noting that despite the slowed traffic the situation is probably more hazardous for pedestrians because the traffic now takes more of their time and attention.
