Designers Jae-yun Kim and Jong-Su Lee have devised a stunningly simple concept for the humble speed hump.

The idea is simple enough: each speed bump is fitted with retractors that stay closed (flat) if a car hits it at below 30km/h, and open (bump!) if a car hits the bump at any speed over 30km/h.

Kim and Lee’s speed bump concept has been created to reward those of us who agree with the need to drive slow in residential areas, school zones, and shopping complexes, and punish those who don’t.

f**king great idea i reckon. will save many repairs. many shopping centers have speed humps that are just to tall. for instance i of a few that i wouldn't take my girlfriends pulsar over. and its standard 4wd height

So if u drive above the speedlimit the speed bump catapults up?? where does it detect the speed? on impact or a sensor beforehand?

hm...all up, sounds interesting, but won't ever happen in Australia.

im capped so cbf clicking the link, but is there alot of electronics involved?

you could almost achieve the same result by having a strut/shock absorber between the two halves, with the right valving, it could lay down flat (extened shock right out) at low speed, but if your going to fast, the shock wont close up fast enough and you have a bump, make sense? might need a little ramp, long and flat, leading up to the bump to assist it laying down ahead of time but meh, i'm not a civil engineer, you work out the details :)

im not too clear as to how it works...doesnt help that i skimmed it but it opens up if you hit if over 30ks which may mean you wont be ready for it when it pops up and your rears hit it and throws the car into the wall..lol I can only see this in shopping centres, big corprorate business parks the like then again you dont normally do more than 30ks in places like that anways. too many moving parts for the average road which is where speeding usually occurs plus im sure a big ass truck or two would make mice of it. good idea non the less.

Yeah, I wouldn't mind seeing them installed in carparks.

I can get in to my local Westfields, but I can't park on the roof because their metal speed humps scrape the undercarriage on my stock ride height car. A mate tore the mid muffler open on his S15 there.

must be a wesfields thing. my local one has the same problem. my mums rio/my girlfriends pulsar all scrape and are all standard height. then they put a new section in and they are even worse. seen standard 300zx rock on the sill trying to get over one.

EXCELENT IDEA! but why would the government spend $1000 on this smart speed bump (estimating here) to please a small group of enthusiests ( us ) when they can just spend $200 (again an estimate) on a slab of concrete.

it would be awsome for these things to be used but i dont think its ever going to happen.

    • You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster. 
    • Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!
    • That dirty voltage drop is the culprit I suspect 
    • i cant get them all in 1 screenshot unfortunately as i just dont know how to move things around tbh, but they are all from the same log and the line crosses at the same point for all of them
    • It's about time I start work on my sun tan. So I knocked up a few parts that will all combine together to become my new power steering reservoir. Now just to produce an abundance of UV and IR rays while melting a heap of bits of alu to become one... Well, that's after I put one more hole in it for the return line to plumb to. It likely won't be this weekend, as Sunday I'm meant to be in doing some last minute stuff to the AMG race car, and the weekend after will be filled with non my Skyline stuff, followed by Bathurst 6 hour. So I don't expect to get to melt metal for at least 3 weeks.   I also managed to stuff up and start cutting the hole for the res to pump pipe on the wrong side of the line... It means instead of the lines being nice and tight against the inner guard, they'll be out off the guard.    The size of it means I should end up with about 1.8L of power steering fluid, and still have space for another half a litre before it reaches the overflow/breather. This is wayyyyyyy more capacity than factory, which should help keep Powersteer oil temps lower, and the design hopefully allows it to prevent any aerated oil being able to makes its way down to the bottom as it'll have a couple of baffles and some hopeful trickery to force air bubbles away from the bottom.
