nobody should ever be allowed to drive ever then
Perhaps - automobile-related deaths outnumber gun-related deaths about 30:1.
And that's not to mention all the deaths from diseases associated with air pollution.

Agreed, robot cars when?
Cars using ML will at times have to answer to philosophical questions such as trolley problem.
Honestly, no they don't. If the car is following all applicable laws, no one should ever be in any danger. If someone has violated the law, they have inherently accepted the risks of their decision, and thus the car should protect the occupants.
Someone tied to the street, doesn't apply because (in my state) the car should be moving at a speed that it would be able to stop in time. Someone thrown from a bridge into a cars way isn't one either, the car should try to protect the occupants again, because that's the case where it'll do the least amount of damage to other nearby cars. In the latter case, Humans wouldn't be able to make a moral decision in that amount of time either, and thus, should default to doing the least amount of damage.

Clever how you use the phrase these guys to underscore your belief that what they're doing is a good thing. I, on the other hand, agree with the other commenter that "it sounds like a terrible world honestly", and I have a negative view of this startup. I would probably something formal to describe the people working there, just like I would people working at Elsevier.
I would compare it ethically to working for or investing in the private prison industry.
Ooh, that makes perfect sense.

maybe we should put some thought into how we can make sure the police use it properly. This times a million. Do not just make the device accurate, make sure it is very hard for a motivated individual to trick it into being inaccurate, in either direction. Please excuse the terminology, was learned from very elderly engineers, but above foolproof (stupidity), there is twatproof (deliberate misuse) and cuntproof (educa…
reading HN as a woman is an exercise in managing fury
My apologies if I have caused offense. I have angered you here and this wasn't my intention.
One thing I will say is that the prefixes I gave are in general use as descriptive epithets by both men and women across much of the English speaking world, along with many others decribing the male genitalia, with much greater frequency than you will find on here. Personally, I'm with Alice Fraser on this one - https://www.youtube.com/watch?v=gioul9PW9B0 - but will cheerfully adapt the taxonomy in future, if I can find better words to use for the prefixes. Any ideas?

#365Please, for all of us, make sure your test set contains a wide diversity of people - doing this testing on recruits from a local college or among friends would make it very easy to bias your results for accuracy on particular populations. it's critical that your device be equally accurate on tall people, short people, white people, black people, men, women, thin, fat, and people with various illnesses or other disord…
Excellent point. This is something we have talked about internally a lot. Early on, we are really testing whichever people we can get but when we move into a full clinical trial we are definitely going to design the study to be as diverse as possible. That is why we reached out to Curebase, to make sure the professionals were involved.

#366The Draeger breathalyzer fiasco in Washington State was mentioned elsewhere in this thread. Draeger has consistently resisted attempts to make its source code public. Will you commit to publicly releasing the source code to your "cannalyzer" device firmware?
Nice name for the device! To be honest, neither of the founders are electronics or software people, we are nanotech engineers. I don't actually know how useful the source code would be for determining if our device is working as intended. We would certainly release information regarding how our device performs QC checks and have the device validated by a third party.

#367>Whereas a blood alcohol concentration of 0.08% (the legal limit in most states) might result in a concentration of 208 ppm of ethanol in the breath, a similarly impairing dose of cannabis results in 0.00001 ppm of the drug in breath. Hi, I'm just curious if you have any reference to help elaborate on the similarities of imparment as it relates to negative impact on a persons abilities (especially those known to have…

You are totally correct that alcohol consumption results in far more fatalities and injuries than cannabis. A big part of this is how much more prevent alcohol is than cannabis. While around 70% of people report having used alcohol in the last year, only 20% report having used cannabis. However, this is changing as more and more people are using cannabis every year. I think we are going to see a long term trend were cannabis starts to close the gap with alcohol, at least where the drug is legal.

#368Dumb question - does the way the cannabis was consumed affect the accuracy of the device? Does it work as well for edible cannabis as it does for a joint?
Re: Launch HN: SannTek (YC S19) – Breathalyzer for Cannabis
#369Shouldn't you need to prove that cannabis inhibits your driving first?
There is actually a lot of peer reviewed articles supporting the fact that cannabis impairs driving. Here are a few articles you might be interested in.

#370I remember reading a story about a Grandmother who ate a strong pot brownie everyday for medical reasons and it had little noticeable effect on her. We know there's a direct correlation between alcohol levels and driving impairment, but I've not seen evidence for this link with THC. Are there studies that have found this? (Please forgive my ignorance...) If someone uses X amount of marijuana (what this tech can estab…
Excellent point. I'm not sure how "fixed" the correlation is for alcohol though. Someone who almost never drinks will be quite impaired at 1‰ BAC, whereas someone who drinks several times a week might not be affected that much. Of course this variation is comparatively small. When it comes to THC, individual resistance really differs by orders of magnitude. Seems the body can adapt to psychoactive agents more easily…
At 1% BAC you are dead, dude
