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

Are you always driving exactly 5 MPH in a garage?

I seriously doubt this is going to damage vicious speed freaks driving 8mph, pretty much no matter what it's made of.

Mercedes has a neat solution for speed bumps as well. "Two cameras located at the top of the windscreen scan the streets and setup the suspension to absorb the bumps." https://www.youtube.com/watch?v=RQsMfHg6jIE

Neat meaning "does not have to slow down and can keep on killing pedestrians"?

Despots of this world know how to drive in style.

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. :)

I really appreciate the brutal honesty of your initial comment! Of course there is a vandal in every single one of us and those who say otherwise (or downvote) are in denial.

That may be true of many, but certainly not everyone. I find most vandalism to be pretty morally reprehensible, since it does damage to another person or to society as a whole, for no benefit besides momentary enjoyment. I have significantly more compassion for a thief than a vandal. (Of course, these feelings would be somewhat proportional to the degree of damage caused.)

Taken a step further, could LIDAR/RADAR systems detect speed bumps and inform the suspension system?

Watch the Bose suspension videos; they include a car vaulting over road obstacles.

AFAIK, that whole effort is pretty much dead.

"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 was speeding laden trucks.

It looks like a great MVP, and within car parks would guarantee an almost predictable max load weight.

Shouldn't speed bumps be designed that you move over them at the speed allowed there, e.g. 30 km/h? So theoretically there wouldn't be a slowdown, unless you're already going faster than allowed. At least I haven't seen speed bumps in 50 km/h roads just to slow people down.

Should, probably, but it's common in Central Europe that on a 50km/h road, there are 2 speedbumps that can't be safely passed if you're going over 25km/h.

Here in germany, mostly due to tech that allows speed-bump avoidcance, most villages and citys use a sort of slalom that by virtue of physics enforces a speed limit.

Also beloved are narrowings to one lane, where you can not see until you are really close up, wethere somebody from the other side is entering the lane.

My guess is their nemesis, the snowplow.

it's a Spanish website, presumably an invention from a Spanish company. I wonder if a Norwegian customer said "What about snow?" and all the engineers thought "Oh...".

You still have to brake (brake pads and discs suffer for no reason), gear down (transmission suffers) and potentially move off at a low speed (clutch suffers, your wallet suffers if you go over them frequently). Even at minimal speeds (less than 20 km/h), speed bumps feel very unpleasant and I really don't like sounds my car is doing while riding over them.

And also more emissions are released into the atmosphere due to an interruption acceleration cycle that resembles that of a traffic jam. But then I'm not sure even if a viscous speed bump would help there. We need tech that will eliminate the need for speed bumps - of any kind - and speeding tickets.

This is worst when you're forced to shift into first gear, when you can ride over the speedbump in second or third, it's okay - and these speedbumps would allow it.

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)

Sounds like expert-level trolling ;)

These are speed-bumps near my mother's house in Wales: https://goo.gl/maps/hdThhzduxpp – they're sort of trapezoid, they work to slow traffic, but above a certain speed you definitely feel less of a bump too.

Speaking to a founder to a competing company ( https://www.edeva.se/en/ ) I found out that there has been many attempts at solving the problems of speed bumps: - Everybody gets bumped, not only high speed vehicles - Emergency vehicles need to slow down - Bus drivers and others can get back problems from speed bumps Most solutions break down because the forces and the wear and tear is so tremendous. The solution from…

I've always wondered what it would look like to tie one of those roadside speed monitoring trailers (they have a sign telling you the speed limit, and your speed) which were in contact with a 'speed bump' filled with hydraulic fluid. The faster you go over the limit, the harder and taller the speed bump :-) If you did this with a camera system you could avoid penalizing emergency vehicles.

Or a significantly more expensive (and correspondingly reliable) infrastructure investment in two traffic lights, where speeding past the first one triggers the second. Also requires: two intersections; cameras and/or law enforcement to enforce an actual penalty.
