Immediately brings to mind the shield exercise in Dune which only the slow blade can pierce. Can't recall if it had a name.

It didn't have a name, that was just how the shields worked - they opposed motion, so only slow-moving things could pierce them.

Earlier quoted context omitted.

How many public lighting bulbs and metro card readers have you broken recently? Those are all more fragile than this.

None, because nobody hates lighting bulbs or metro card readers, while every driver hates speed bumps. Well, maybe not all drivers, but one driver who hates that damn speed bump that he has to drive over every day is enough to make that baby bleed. :) I'm just being realistic. I've lived in an impoverished area all of my life and I know how things here work. I'm saying what I honestly believe would happen with these.

You might be right that they'd be vandalized. I expect you're getting down votes largely for suggesting you'd do it yourself.

Very cool!!

Out of curiosity, why is it only available indoors?

What I meant, although I guess it wasn't clear, is that from my own experience a vandal is many times not what you expect him to be. Sometimes, he's some guy with glasses who posts on Hacker News. And sometimes, that vandal is not a he, but a she. I've seen it all. :)

Does it allow emergency vehicles to proceed quickly? :/ That's my main criticism of speed bumps

They are rarely placed where the prudent maximum speed is much above the posted speed. I guess if there is a patient in fragile condition in the back of an ambulance that would be an issue.

Come to my city. Many limits are based on non-safety things like road noise and antiquated notions re saving fuel.

Speed bumps are common in places like huge parking lots where reasonbable varies wildly throughout the day.

Bumps are also used to bring traffic down well below the posted limits.

first guess: They haven't gotten UV protection right just yet.

This is going to be fun. Some people will learn that it's soft at slow speeds and will assume it's always soft and severely damage their cars.

No tears shed by me. Speed limits are to be obeyed, not ignored.

Are you always driving exactly 5 MPH in a garage?

From the first video:

> “Whether you respect the speed limit or not, your car will suffer from a speed bump regardless.”

Can anyone confirm this? I would assume the suspension can handle speed bumps fine at low speeds. That’s what it feels like from inside the car anyway.

Couldn’t it be argued that, as we approach a speed of 0 mph, there exists a speed at which no damage is done to the car whatsoever? And, if we place speed bumps accordingly, there is no need for this technology — particularly considering the difference in cost and maintenance?

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?

It’s so that when you go the appropriate speed you don’t feel the bump.

Which can reduce damage of delicate loads, like ambulances. I expect it would reduce wear-and-tear on suspension of heavy vehicles too.
