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.

    • A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.
    • The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?
    • So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...  
    • the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
