"BIV baden inteligente de velocidad This Intelligent Speed Bump (BIV) is based in Non-Newtonian fluids dynamics in which particles in natural movement as liquid align when receiving an impact, thus entering into a solid state. This fluid is also biodegradable and harmless for human beings.This fluid inside the BIV is the solution to vehicles at sensible speed that will find no obstacle when driving over it. The other…

Very cool!! Out of curiosity, why is it only available indoors?

My guess is their nemesis, the snowplow.

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

They were the result of a Holtzman generator and was an attribute inherent to shields rather than just the shield exercise. The actual slow vs fast aspect was never given a name per se.

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.

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?

Well, let me give you one reason why: Last year I got launched by a speedbump on my bicycle and broke my leg in six places. I could have really done without that given the fact that I wasn't exceeding the speedlimit and wasn't driving a car.

I believe only in Russia does a speedbump launch someone and in America, you only launch yourself off speedbumps.

Apologies if joking about it is too soon =P

Unsure how this fluid bump would affect bikes - maybe it has too much traction and you get launched over the handles at certain speeds?

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.

Being Spanish, I know someone will stab those with a knife or a screwdriver the first day they are installed. That someone might even be me. I mean I'm happy they are proud of their invention but, please. Don't make me laugh.

Add a fine mesh and connect the mesh to electricity like a cattle fence. Insert screwdriver and... ZORCH! Muahaha.

what screwdriver are you using that has conductive handles?
