I stopped watching the video when they put a sexy lady dipping a finger in the liquid. Seriously it's 2017, you're trying to sell technology and you still objectify women.
Would you like to perhaps list the types of appearance that you deem permissible?
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…

It only worked so well because they rigged the tests. The suspension was tuned for exactly each demonstration, it wouldn't work under normal mixed conditions. The system was also extremely heavy and used a boatload of power for the actuators. A well-setup conventional suspension system works nearly as well for anything you would encounter in the real world, and it's a lot less expensive. Even Citroën (the kings of hy…
Ignoring street-legality and commercial feasibility, if the Bose suspension is automatically adjusted using feedback from e.g. LIDAR and/or depth cameras, wouldn't that solve the "tune for each demo" problem?
A student startup built something similar for potholes, which i think is a better use of the tech (1). Essentially road repair crews could carry a couple bags of the fluid and drop the bag into a pothole, where it would confirm to the shape of the hole while stiffening on impact from the tires. Unsurprisingly this was invented in Cleveland. 1. http://www.popsci.com/technology/article/2012-04/bouncy-thic...

> Unsurprisingly this was invented in Cleveland. For us uninitiated - why? Quality if the roads there?
Another commentor explained how potholes form, but I'll add that Cleveland doesn't have a lot of money and tends to defer maintenance. When I was living there, road signs saying "Steel Plate on Road" were a common sight. I remember the city fixed a water pipe and instead of re-paving the street, they just left several giant 4ft x 8ft steel plates with corresponding sign for over a year.
I live about an hour south of Erie, PA and the road I travel to and from work has needed resurfaced after every winter over the last 3 or 4 years.

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.
The main issue is that everything movable or deformable is going to get absolutely wrecked by vehicles, in short order. Even old-fashioned speed bumps get severe ridges worn into them by vehicles that go too fast. They need to be repaired after a year or two. And even if that doesn't happen, they experience severe forces from wheels, every single day. You (and the non-newtonian bump mentioned in the article) suggest…

Very cool!! Out of curiosity, why is it only available indoors?
I think it's only available indoors because it's secretly filled with mayonnaise (non-newtonian fluid.) But on a serious note, it's plausible that whatever they've filled the bump with degrades under temperature conditions outside of what you'd find indoors.

Speed cameras are slightly more expensive than a speedbump and way easier to sabotage. It's enough with some paint to disable it temporarily or just cut it down if you want it disabled a bit longer.
The ones out on the highway here have just tended to get shot at I think.
