Hypermiling vs speed bumps

[Piwoslaw]

The speed bumps are definitely there for safety, not FE, so slim chance of getting the neighbors to remove them. Especially since I also don't want to step out of my entrance gate in front of a car that is trying to break the sound barrier.
Without speed bumps: most cars go 40-50 km/h, but many (25%) go as fast as 90 km/h.
With speed bumps: most cars go 30-40 km/h, while about 10% floor it and accelerate to 60 km/h and suddenly brake hard, then again and again.
Mind you, this is a small residential street with intersections every 100m.

i hate doing that to the car but i will not let a sleeping policeman tell me how fast to go.

That reminds me of a joke: What kind of car can take a 12 inch curb at 45 mph? Someone else's.

There was a post here somewhere about an active speed bump that would lower if the car was going slow enough. I can't find it at the moment.

Wish my street was peppered with monstrous speed bumps.

This reminds me of the "active suspensions" out there that could pull back just as fast as the speed bump rises, and you could go over it at 90kph and not feel a thing.

Edit: Here those are. Sixty seconds into this video:

I have 5 BIG round-top bumps on my final approach to work, and departure in the evening. I take them at 15 mph (parking lot) speed, so I don't have to do one last pulse. Taking them at street speeds, though, I don't know.

The Odyssey van, on the other hand, gets all out of sorts on the same bumps. Wheel hop, skittering sideways, wallowing. And I chose the Ody because it's one of the best-handling of the minivan bunch. It's still a tiptoeing hippo.

What is the world's fastest production road car ?
Any hire car.

We have speed humps on our street and I'm happy with them otherwise we get the usual morons doing 50 in a 30 zone. We still get the occasional moron in a 4x4 doing the same. They are designed to brake springs at over 40 but be smooth at 20.

I match my speed to the hump design so about 20. As I crest the first one I pulse to the next one and arrive at about, or just under 20 and go over and repeat. If nobody is behind I can pulse and take two of them in one glide. If I'm being tailgated (X-5 driver usually) then I glide for more than two.

My real limitation for P&G in my street is parked cars and everyone else playing chicken passing them. I had this on Friday - a black cab no less deciding to pull out onto my side to pass a line of cars despite me coming the other way with my lights on. I think he expected me to go ont he pavement to let him past.

So it was time to stop, put the handbrake (aka parking brake) on and wait. After all he's paid by the mile behind the wheel, I'm on my way home from work

There is an "active" suspension system for negotiating speed bumps and potholes, but there are a few gems out there that require hyperactive suspension.

My front tires actually spin a bit and chirp as they hit the ground if I go over a bump too fast. It has a lot of torque on idle.

I would blow the horn on and off for about 5 seconds when I slowed for the bumps they might recommend that the bumps be removed after hearing all the protest. I understand people wanting to do something to prevent speeders from zipping down the street at unsafe speeds but to hold all drivers hostage because of of a few is unamerican.
Rather than speed bumps they should set up a camera radar system and nail speeders all the way to the bank. Some roads the speed limit is not accurate others the speed is too high. For instance there is a road that has a speed of 35mph the road is straight 3 miles long light traffic people are going to drive down that road around 55 I do 35 but they act like I am a weenie for doing the speed limit. Other locations have 65 mph homes close proximity to the road heavy traffic and hardly any room to accelerate to the speed limit.

I would get your license and... who knows... you would soon have a reason to stop doing that.

That camera should be equipped with a microphone to record instances of motorists disturbing the peace with unnecessary horn blastings.
