My guess is their nemesis, the snowplow.
how do normal speedbumps deal with snowplows?
This would work for non-Newtonian speed bumps as well, though the first time a plow driver doesn't see the sign, and there's always going to be one who doesn't see the sign, you end up wiping out the speed bump instead of just dinging it.
Can someone enlighten me on why we need a smarter speed bump? If cars going too fast are going to be damaged either way, there's no benefits on that end. If the motivation is that cars can go slightly faster overall over the bump to reduce traffic... then don't put a bump there!?!? Slow traffic will still be slow?
Sometimes there are big long speed bumps that are actually MORE comfortable to take at higher-than-legal speeds. And it's encouraged an arms race in vehicles in the US; it undoubtedly influences people to buy bigger/heavier/taller vehicles with longer-travel suspension.

"Raise Plow" road signs near the speed bump. This would work for non-Newtonian speed bumps as well, though the first time a plow driver doesn't see the sign, and there's always going to be one who doesn't see the sign, you end up wiping out the speed bump instead of just dinging it.
I'd also be concerned about the effect that widely changing temperatures would have on the viscosity and hence critical speeds. It'd suck to install one in summer, get used to driving over it at 40km/h, then during the first cold snap find out it'd turned as hard as rock.
I suspect this was a problem that didn't need to be solved.
Does it allow emergency vehicles to proceed quickly? :/ That's my main criticism of speed bumps
I think that that is exactly the reason why this will not get used. Many speedbumps are actually designed in a way that they are imperceptible when you go sufficiently fast (80km/h is usual)

It’s so that when you go the appropriate speed you don’t feel the bump.
I wonder if that would make people drive progressively faster over a stretch of road until they notice the bump. Or more common, people will speed towards the bump and again, brake right before it.

No tears shed by me. Speed limits are to be obeyed, not ignored.
Are you always driving exactly 5 MPH in a garage?
