Retractable Speed Bump awards Slow Drivers *New must see*
 

I saw this just now on a website I visit really often, its a speed bump that will not go up if you are going slow enough, will if your going fast, would be great for us eh? :p Retractable Speed Bump Awards Slow Drivers - Geekologie

Or you could just blow through speed bumps fast enough that the suspension passes over the speed bump before the body has time to react. Try it some time.

All the more reason ridge the retractable speed bump with tire spikes.

:thumbup:

Why have people think for themselves when you can force them to do what someone else deems safe?

I dont like the idea speed bumps at all. Its debatable if they even help at all and its just one more thing that ruins driving.

This design could fix a couple of the problems associated with them, but at what cost?

speed bumps piss me off, unless they're in a real hazard area (school zones) all they do is hold up traffic and waste petrol. Luckily the bumps on my commute can easily be driven over at 60kph+ unless i get idiots that slow down for them

The problem with speed bumps is that small cars really have to be careful, while SUV's hardly notice them. There is no standard size/shape for speed bumps here, so each one is different. Some tall, some steep, others wide. There is a bump in my neighborhood that regularly catches low cars, the driver has to get out and push. Lots of scraping sounds.

The retractable bump is a good idea, but how fast can it react? And will the height be different for different cars and speeds? Like for a speeding SUV's, instead of a bump you get a concrete wall.

Yeah my 1ton goes "hmm, think i hit squirrel, oh well" while the saturn (RIP) nearly panicked when she got close to one.
In our area they are using speed humps instead. Bumps are shaped /-\ while speed humps are more /------\ they are long enough that low cars dont get stuck. the design is effective on SUVs as they are matched to the wheelbase. when the front tires are going down the front, the rears are just hitting the back. They are not to be ignored !!! Tried that in a work van and threw half the contents out of the shelves.

If I see speed bumps, I speed up. I mean, they're SPEED bumps, aren't they? If they're in a business parking lot, I'm pretty likely not to go back and shop there again.

I like your way of thinking xD

reminds me of cornstarch (or some other non-newtonian fluid), or a Tibetan monk maybe.

Reminds me of the opposite.

if you hit the cornstarch quick, then it firms up. push slowly and it yields.

Oh, I was thinking something along the lines of...

---v--- where the "v" is a recess full of cornstarch


you are saying
---^--- where the "^" is somehow held in shape and if you go across slow it lets you go through.

Let's see how well they function in the great frozen north. Or how long they even stay in place after a snowplow.

I wonder how it accurately measures the vehicle speed. A 2000 lb car should produce half the force at the same speed as a 4000 lb car. But in either case, you have to hit it regardless. So assuming the speed measurement works properly, if you've got a low slung car or spoilers or whatever, you're going to suffer damage even if you're going the speed limit.

I avoid places with speedbumps as well. There isn't a single speedbump or speedhump I know of that you can drive over at the legal posted speed without damaging your car. You have to come to a near complete stop and crawl over them.

speed ditches work much better than speed bumps, for all vehicles.

try to ignore one and you thrash your front bumper and suspension

not only that, but they effectively shuttle water from one side of the road to the other.

I'm all for uniformity on these things. On my 1st bike tour, I returned to a nice campground. Turning in to the driveway down to a river, I thought to myself - Ahh! First time in a week I'm on familar pavement! Then I discovered that they had added speed bumps, and not gotten them painted yet, in an area of dancing tree shadows.

It probably records speed some distance ahead with a laser speed detector. Relying on force to deduce speed is very unreliable. EDIT: Yup, it's very unreliable... and they're still going to use it that way. No laser detector.

Trailer park I used to live in, a bunch of the residents got upset over a speed bump being installed in the main driveway. They began going the wrong direction up the one-way road to avoid it. I did the same, because my vehicle would get stuck on the speed bump. It was like 10" tall, with no obvious regard to grade transition. My car had less than that for clearance, by far.

Speed bumps tear up heavy service vehicles such as fire trucks and ambulances that are covered in, or filled with their assorted equipment.

As far as I can tell they do nothing to improve safety. They just annoy people and cause congestion and speed shear.

I go the speed limit over them, personally. It always ticks me off when I see someone in a smooth-riding luxury SUV take speed bumps at 2mph.

Have you guys ever seen speed tables? I've seen them in Massachusetts. They're just like speed bumps, except they're like 10 feet long. I can normally go over them at like 25 mph without even feeling them. I really like them because they keep people from speeding, but don't force them to jam on their brakes right before it.

My Civic Si doesn't have enough suspension. Iv done it in a car with enough, and it will help, with most cars...

Yes, I have taken train tracks faster than the behemoth SUV behind me.
