Does it allow emergency vehicles to proceed quickly? :/ That's my main criticism of speed bumps

#82Being Spanish, I know someone will stab those with a knife or a screwdriver the first day they are installed. That someone might even be me. I mean I'm happy they are proud of their invention but, please. Don't make me laugh.
Put one in a rural area and eventually someone will come along and shoot it.
That's what happens to absurdly low speed limits and moronically placed stop signs. I don't see why a speed bump would be any different.

#83From the first video: > “Whether you respect the speed limit or not, your car will suffer from a speed bump regardless.” Can anyone confirm this? I would assume the suspension can handle speed bumps fine at low speeds. That’s what it feels like from inside the car anyway. Couldn’t it be argued that, as we approach a speed of 0 mph, there exists a speed at which no damage is done to the car whatsoever? And, if we plac…
You still have to brake (brake pads and discs suffer for no reason), gear down (transmission suffers) and potentially move off at a low speed (clutch suffers, your wallet suffers if you go over them frequently). Even at minimal speeds (less than 20 km/h), speed bumps feel very unpleasant and I really don't like sounds my car is doing while riding over them.

"Raise Plow" road signs near the speed bump. This would work for non-Newtonian speed bumps as well, though the first time a plow driver doesn't see the sign, and there's always going to be one who doesn't see the sign, you end up wiping out the speed bump instead of just dinging it.
Maybe you could have protective ridges at the side of the road which would act as hard stops for the plough while staying out of the regular path of traffic? I'd also be concerned about the effect that widely changing temperatures would have on the viscosity and hence critical speeds. It'd suck to install one in summer, get used to driving over it at 40km/h, then during the first cold snap find out it'd turned as har…

Maybe where you live. In the Seattle area[1], speed bumps are frequently installed on residential streets where the actual limit is 25-30 miles per hour (40-50 kilometers/hour using non-legacy units). It's typically done in "problems areas" where a small number of people drive 25-50% or more over the limit, but it's extremely frustrating, because it forces drivers to drive way below the actual limit when crossing the…
So if this kind would be installed, then they'd be soft at regulated speed and only solid at speeds significantly exceeding those. I doubt you'd be able to sue the city for breaking your car then - you have been warned. Still, no tear shed.

It's supposed to be like a rock at 40km/h anyway. You're supposed to slow down to 5-10km/h

#89Speaking to a founder to a competing company ( https://www.edeva.se/en/ ) I found out that there has been many attempts at solving the problems of speed bumps: - Everybody gets bumped, not only high speed vehicles - Emergency vehicles need to slow down - Bus drivers and others can get back problems from speed bumps Most solutions break down because the forces and the wear and tear is so tremendous. The solution from…
I've always wondered what it would look like to tie one of those roadside speed monitoring trailers (they have a sign telling you the speed limit, and your speed) which were in contact with a 'speed bump' filled with hydraulic fluid. The faster you go over the limit, the harder and taller the speed bump :-) If you did this with a camera system you could avoid penalizing emergency vehicles.
Yeah I've always felt like speed cameras should have been the "disruptive technology" for speed bumps but we're lagging behind for some reason, instead choosing to penalize everyone using the road.
How often are speed bumps not doable at the speed the street allows, e.g. having to go 15-20kmh over the bump in a 30 zone, or more extreme, 5kmh in a 50 zone when they want you to watch out for drunk pedestrians during events when said pedestrians aren't there (or drunk) yet/anymore...

Here are three problems I see:
- it has electronics and actuated parts - will be a maintenance issue
- it can be overridden remotely - yet another thing in the city to hack for fun or profit
- there's a distance between speed measuring zone and the bump zone that's big enough the device might react confusingly in dense traffic
