Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:Yeah hand signals (278 comments)

Given a system that can track changes to your trajectory in space within millisecond time frames it is likely that any autonomous car will know what you are doing without any need to signal it.

It will also have situational awareness. So will be able to make predictions of likely behaviour. E.g. if you are in the bike lane, near a corner and make a slight swing out to the right it will wait to see if you are going to lane change to turn left or start back the right to make a right turn.

All of which most drivers wouldn't even notice as they have limited attention and that may be directed somewhere else through an intersection.

Yes, better to kill 30,000 plus people every year. It is simply inconceivable that there might be a better solution.

Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:been wondering many similar things (278 comments)

The owner of a parking lot could engineer in the specific parking locations he wants cars to use and the cars will automatically park exactly centred on them without a problem (thanks GPS..)

Alternately, once a large number of cars are autonomous they can drop you off at the door and then go and park themselves. Also they can pack themselves in as the current "parked" cars can move to allow them in and out. A parked autonomous car can move around in the parking lot to suit current requirements. All of which means that the number of parked cars is higher so parking lots can be smaller.

Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:A Pile Of Money (278 comments)

If cars (automated or otherwise) are using the roads, then data about its current condition and any changes will be available. The more cars that use a route the faster changes get propagated.

You have heard about this thing called the Internet? It does work I'm told from within moving objects like cars thanks to LTE and 3G.

Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:Hype (278 comments)

Its called street view. See how much of your local city has been scanned. They already have a fleet of cars doing this.

Just a matter of beefing up their street view cars to collect any additional information they need and when they make their next pass through your neighbourhood you will have been scanned.

Analysing the data is just a matter for big iron. And Google is getting very good at building out that required infrastructure.

The Google concept car can be used now.

Think campus, airport shuttle, gated neighbourhoods, retirement communities.

Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:Baby steps (278 comments)

Correct, there may be situations where the best of the best of skilled human drivers will do a better job.

On the other hand most drivers are simply not that good.

Unfortunately 80% of all drivers THINK they are that good. Some of them MIGHT be that good a small amount of the time, but not ALL of the time.

Autonomous cars will attain a specific level of competence (which will improve over time) and will operate at the level all the time. They don't get impatient. They don't get tired. They don't text. They don't try and pick up the soother in the back seat that the baby dropped (yes, recent cyclist death was due to driver doing that.)

Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:Baby steps (278 comments)

Hmm, in most places as soon as the snow hits the ground human drivers prove that THEY cannot drive on snow either.

I suspect that this is another intractable problem that won't actually prove to be all that hard to solve. Where solve simply means doing a better job than 90% of the human drivers out there.

Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:columns of pixels? wrong. (278 comments)

Hm, no interpolating the trajectory of a moving object in space is something that the best physicists, mathematicians and computer scientists simply have not been able to solve. It is an intractable problem that can only be solved in real time by organic brains.

Of course the Iron Dome might just be a counter example (those sneaky Israelis obviously didn't get the memo!)

Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:can it get me home from the bar? (278 comments)

99.9999% of human drivers!!!!!!

Give me a fscking break. You obviously don't actually ride around cities on a bike.

I spend a huge amount of time on a bike. I'd be happy if 75% of drivers paid attention. Simply put, human drivers DO NOT pay attention at the best of times and don't see cyclists a large percentage of the time.

One of the reasons I want to see only Google cars on the road is BECAUSE I'm a cyclist and figure my chances of staying alive will improve dramatically.

Hidden Obstacles For Google's Self-Driving Cars

sl149q Re:can it get me home from the bar? (278 comments)

You miss the point. Hitting anything at speed can injure the occupants.

So you need to treat anything that could possibly move into the path of the car as a potential threat.

That includes bikes, kids, pedestrians, deer, coyotes, moose, skunks, dogs, teenagers carrying trashcans or other large objects, etc.

That means slow down and keep a safe distance. Hmm. Just what human drivers are SUPPOSED to do (but often don't.)

Islamic State "Laptop of Doom" Hints At Plots Including Bubonic Plague

sl149q Re:Self-Inflicted Damage (360 comments)

Yes, it probably would reflect back to their own population.

a) they don't care
b) they would blame it on the US
c) they would blame it on the Israelis
e) they would call them martyrs
f) they don't care

DoT Proposes Mandating Vehicle-To-Vehicle Communications

sl149q Re:Hacking (258 comments)

No different from phoning in bomb threats.

And likely to result in the same jail time if you get caught.

At some point use of the normal societal methods for dealing with criminal behaviour works best. It can be the least expensive way to go.

DoT Proposes Mandating Vehicle-To-Vehicle Communications

sl149q Re:Short range transmission =! privacy concern (258 comments)

To be fair, as soon as a vehicle is broadcasting any information it can be received and recorded.

For example every overpass can have a radio and record all information from all cars passing by.

That IS NOT a reason to not do this. And in fact makes a lot of sense as it can be used for lots of interesting and good purposes (if nothing else to keep the Google map traffic information up to date.)

DoT Proposes Mandating Vehicle-To-Vehicle Communications

sl149q Re:Motorcyclists rejoice! (258 comments)

Bike riders complain that cars and trucks break the law.

Motorcyclists complain that trucks and cars break the law.

Cars complain that trucks, cyclists and motorcyclists break the law.

Commercial drivers throw their hands in the air and complain that everybody else breaks the law. Ditto for bus drivers.

To get all biblical... And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?

Which is also why 80% of all drivers (of all types of vehicles) think they are above average in driving skill and behaviour.

It's Easy To Hack Traffic Lights

sl149q Re:So when are we going to hear (144 comments)

This is really not much different from simply (for example) removing traffic signs.

I recall that some kids removed a stop sign as a prank, (Florida, mid 90's?) There was a bad accident and the result was a man slaughter charges and something like 20 year sentences.

It's Easy To Hack Traffic Lights

sl149q Re:people charge of traffic lights are engineers b (144 comments)

Well our local municipal engineering department obviously has not read that memo.

We have various lights that are always green and switch on demand when a car approaches on the side street.

I'll note that the counter argument is that people using those roads get used to them always being green, but also get used to them switching quickly to red when a car approaches from the side street.

Google Government Request App

This new Google App: http://www.google.com/governmentrequests/ is their attempt to show how many requests they have received from governments around the world. These can be requests to censor or requests about users or users data. This is a welcome response compared to other ISP's and Telecoms that have routinely denied or ignored requests for any information of this type.

WSJ: Time for a Climate Change Plan B

sl149q sl149q writes  |  more than 4 years ago

sl149q (1537343) writes "Whether you believe in Climate Change or Climategate the problem is that no one in the first or third world is really willing to actually pay enough to change things fast enough to make much difference. The bigger question is whether it is better to spend money to mitigate one problem (CO2) or solve other problems.

This from an article by Nigel Lawson in the WSJ article (http://online.wsj.com/article/SB10001424052748704107604574607793378860698.html) : "The reasons for the complete and utter failure of Copenhagen are both fundamental and irresolvable. The first is that the economic cost of decarbonizing the world's economies is massive, and of at least the same order of magnitude as any benefits it may conceivably bring in terms of a cooler world in the next century."

And: "The reason we use carbon-based energy is not the political power of the oil lobby or the coal industry. It is because it is far and away the cheapest source of energy at the present time and is likely to remain so, not forever, but for the foreseeable future."

And if we do need a conspiracy theory it is helpful to remember that 27 out of 50 of the worlds largest oil companies are state owned or controlled (http://www.energyintel.com/DocumentDetail.asp?document_id=245527)."
