In NZ technically the local-road speed limit is 50kph, but normal accepted practice is to drive at 60. Anecdotally, I get stuck behind someone driving at 40 at least once a week. It's really annoying.
To be silly, I could turn the question around. How do you feel about cars on roads that are slower than 60 kph? We could ban cars on all residential roads and have wonderful walking/cycling communities. When I was living in the UK I was amazed at how many high streets have gone pedestrian. It has reinvigorated small towns.
Of course the problem is, "What happens if I can't get from A to B in my car?" I think for car drivers the idea of banning cars on residential roads makes this point very clear. The same thing happens with bicycles. In many cities it is impossible to get from point A to point B without a car. This encourages/forces cyclists to use inappropriate roads. As the sibling post notes, we need to do a better job of designing our cities.

Considering that cyclists are expressly encouraged to use other roads, this thoroughfare is MUCH more dangerous to a cyclist than most of the rest of the city.
Also: A cyclist will ride at the speed the cyclist can ride. No beef there. The lethargic, social network distracted drivers, however...
FWIW I also have a full motorcycle license, although I gave up my 600 many years ago; I miss doing Phillip Island at 180km/h leaned over. I like to believe that having used multiple modes of transport broadens my horizons.
There are also many places where driving slowly enough to be disruptive to traffic (in the officer's judgment) is an offense.

That section of the vehicle code says, emphasis added: "No person shall drive upon a highway at such a slow speed as to impede or block the normal and reasonable movement of traffic, unless the reduced speed is necessary for safe operation, because of a grade, or in compliance with law." https://www.dmv.ca.gov/portal/dmv/detail/pubs/vctop/vc/d11/c...
If Google's self-driving cars are limited by law to 25mph, and the car was not exceeding 25mph, then it was "in compliance with the law" and 22400(a) doesn't apply. It would be allowed to impede or block traffic, even if we human drivers would really prefer it to be going 45mph.
Sounds like Google's decision to me. Either way, it's not a highway, so that section seems irrelevant. And "in compliance with the law" is quite a broad redirect.
That MV police blog post says the traffic officer stopped the car to "educate the operators about impeding traffic per 22400(a) of the California Vehicle Code."
Sounds like a Dukes of Hazzard episode where the Duke boys are driving a piece of junk and Rosco gets them in his speed trap. They explain that the car is incapable of exceeding the speed limit, so he gets them for impeding traffic.In most European countries there is a minimum speed requirement when driving on thr motorway (usually between 60 - 80 km/h), and sometimes there are even lane-specific speed limits (e.g. left lane requires at least 110 km/h). All that is only relevant if the traffic actually allows you to go that fast of course.
Here in Sweden, highways are off limits if the vehicle may not legally be driven faster than (i think) 45 kmph.
If 24 mph is too slow for that particular road or neighbourhood, then the speed limit should be 45+ mph, not 35. Clearly the average citizen is already driving 45+, or the "slow" wouldn't even be noticeable.
Edit: wait, this is even more absurd. The traffic violation quoted is https://www.dmv.ca.gov/portal/dmv/detail/pubs/vctop/vc/d11/c... which mentions "highway". 35 mph or 56 km/h is residential street speed, not highway speed. This whole thing makes no sense to me.
It's absolutely too slow.
Majority of people drive at or slightly below the speed limit. Driving that far under causes people to start behaving irrationally resulting in lots of lane changes/tailgaiting etc. This can be dangerous when lots of cars are doing it.
That's why the google cars have a little 'aggression' factor which makes them move out a bit without waiting for a completely clear gap.
This means they are legally limited to 25mph and legally allowed to drive on roadways with speed limits up to 45mph.
NEVs let you have very light weight, inexpensive vehicles with exceptional economy… that would be instant death traps in a high speed collision. They don't undergo ordinary crash testing. Think of them as posh golf carts.
I looked into getting an NEV, but most of my local streets are 30mph and I can't in good conscience drive down them at 25mph.
In the case of a NEV, it's a 4-wheel car with doors... Unless told otherwise, most drivers are going to assume they meet passenger car safety standards.
So long as we are mixing drivers and driverless, I think we'll need to close the gap while the problem exists. Laws that reflect driving and better enforcement paired with continual updating to driverless cars so that they can safely manuever in traffic without causing problems.
(in other words, speed itself is not dangerous except in certain situations -- like sharp curves or wet/snowy/icy roads -- speed differential is dangerous)
Nor does it support the claim that "speed itself is not dangerous". If everyone were driving slower, everyone would be safer (which we may actually be able to achieve once a sufficient number of law-abiding robot cars displace human drivers).
No, it was driving 1 mph below the maximum that vehicles in the NEV classification are allowed to operate at, and on a road that NEVs are allowed to operate on. Which is why it wasn't ticketed; it was operating properly.
If you define safety as the risk of your car getting damaged, then maybe you reduce the probability of any kind of accident, without reference to severity.
But you define safety as the "risk and severity of injury,", as almost any person would, the slower you go, the safer you are, under all but a few scenarios, like driving below the posted speed limit on a highway.
Maybe she could build it out of IR LEDs, so it's not obvious to humans. :)

States have similar laws for other emergency vehicles. E.g.: http://www.azleg.state.az.us/FormatDocument.asp?inDoc=/ars/2...
Skip to 10:00 for the police man halting the car, then waving it through.
The whole video is worth a watch, to be honest. It's amazing how well they cater for edge cases.
No different that using a gun and shooting someone by accident.
Are you buying a car that is guaranteed to never be in or cause any form of car-accidents.
Or are you buying a car that will try to it's best to get you from point A to point B.
In an accident with the first example the there is a manufacturing flaw, the car did not meet it's specs.
In an accident with the second example you fucked up, you should not have given the control away and it is your fault. The car did nothing wrong it did what you told it to do.
They apparently registered the small self driving cars as what California calls a "Neighborhood Electric Vehicle".[0] A NEV is limited to 25 MPH, and cannot be operated on a road with a speed limit above 35 MPH. It's one step above a golf cart. Local municipalities can limit their use on faster streets, if they so choose, but they don't have to.
There's a related flap over high speed electric bicycles. They're supposed to be limited to 20MPH, but some can reach 40MPH, and a few can reach 50MPH.[1] They only have bicycle-grade wheels, brakes, and pothole tolerance[2], which is a problem. At what point is a driver's license, or a motorcycle license, required, what's allowed on a bike path, and do you have to have pedals?[3] There are now three classes of electric bikes in California, one of which doesn't have pedals but is still considered a "bicycle". There are also electric mopeds and electric motorcycles.
Trying to fit all these vehicles on the same road and bike path system is difficult.

I'd agree that you shouldn't be in the bike lane at those speeds (though in much of the UK they are few and far between and mostly consist of a bit of paint on the side of the road). That's what roads are for.
AFAIK no driverless cars around here (yet), but there are plenty of other potential hazards for motorists, like pedestrians and bicycles on narrow, twisty, dark and wet streets this time of year.
Ideally it calls for everyone to be patient, careful and vigilant. Above all be thankful if born with great reflexes, on the road alas only a few are so gifted.
