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.

    • Mate you saved be from dying in the Perth summer. AC wasn't changing direction and just going into diagnostics mode fixed it. You're a legend and I would shout you a beer if I could!
    • Unfortunately effort gone to waste, you will have substantial issues with how the manifold and wastegate have been integrated. You would be so much better off with a modified stock manifold like this: https://hypergearturbos.com/product/rb25detexgatedmanifold/   OR literally just getting a off the shelf Sinco or 6Boost manifold as myself and others have mentioned.  
    • Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!
    • Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.
