It was his choice to smoke pot, which led to his skipping school. It makes sense that it affects different people differently, if you want to assume otherwise go ahead. Compared to those who have accidents, "a considerably larger number of people" who drive drunk arrive at their destination with no incident. That would be foolish logic to apply.

My friend knows very well it was smoking pot, he admits it freely and regrets it. It is quite clear in this situation that if he didn't start smoking he would not have dropped out.

Causation is hard to identify in your example though: does smoking pot encourage teens to drop out;

The answer is absolutely yes, it can cause some kids to drop out of school.

I have witnessed my best friend go from a straight A student throughout high school to dropping out the last half of his senior year so he could smoke pot. This set him back a long way, and he had to go back and get a GED 3 years later. It was a clear case of pot's impact on this particular kid, it didn't have the same impact on my or other close friends who all started about that time.

Submission + - Google Lunar XPrize teams partner for a 2016 SpaceX moonshot

An anonymous reader writes: Two competing teams for the Google Lunar XPrize have announced that they are partnering for a mission to the moon in the second half of 2016. From the article: "The Google Lunar XPrize , a $30 million purse of prizes encouraging private teams to put lunar rovers on the moon, this morning took if not quite a giant leap, then at least a big step. Two of those teams, Pittsburgh-based Astrobotic and Japan-based Hakuto, signed on to share a rocket ride to the moon in late 2016. Hakuto, which developed a pair of rovers to explore the lunar surface, will hitch a ride on Astrobotic's lander, which plans to set down in Lacus Mortis, located in the northeastern portion of the moon. Once on the surface, both teams will deploy their rovers and go exploring. The first to cover 500 meters (around 550 yards) while broadcasting high-definition footage will take home the $20 million grand prize."

Submission + - Only twice have nations banned a weapon before it was used; they may do it again (thebulletin.org) 2

Lasrick writes: Seth Baum writes about international efforts to ban "killer robots" before they are used. China, Israel, Russia, the United Kingdom, and the United States are apparently developing precursor technology. 'Fully autonomous weapons are not unambiguously bad. They can reduce burdens on soldiers. Already, military robots are saving many service members’ lives, for example by neutralizing improvised explosive devices in Afghanistan and Iraq. The more capabilities military robots have, the more they can keep soldiers from harm. They may also be able to complete missions that soldiers and non-autonomous weapons cannot.' But Baum, who founded the Global Catastrophic Risk Institute, goes on to outline the potential downsides, and there are quite a few.

Submission + - Driverless Car Beats Skilled Racing Driver For First Time

HughPickens.com writes: The racetrack is the ultimate test of driving skill, managing power, traction, and braking to produce the fastest times. Now BBC reports that engineers at Stanford University have raced their souped-up Audi TTS dubbed ‘Shelley’ on the racetrack at speeds above 120 mph. When they time tested it against David Vodden, the racetrack CEO and amateur touring class champion, the driverless race car was faster by 0.4 of a second. "We’ve been trying to develop cars that perform like the very best human drivers,” says Professor Chris Gerdes who tested Shelley at Thunderhill Raceway Park in Northern California. “We’ve got the point of being fairly comparable to an expert driver in terms of our ability to drive around the track.”

To get the cars up to speed, the Stanford team studied drivers, even attaching electrodes to their heads to monitor brain activity in the hope of learning which neural circuits are working during difficult maneuvers. Scientists were intrigued to find that during the most complex tasks, the experts used less brain power. They appeared to be acting on instinct and muscle memory rather than using judgment as a computer program would. Although there was previously very little difference between the path a professional driver takes around the course and the route charted by Shelley's algorithms until now the very best human drivers were still faster around the track, if just by a few seconds. Now the researchers predict that within the next 15 years, cars will drive with the skill of Michael Schumacher. What remains to be seen is how Shelly will do when running fender to fender with real human race drivers.

actually has a doctorate in aerospace engineering, not astrophysics.

Do you really think if you asked a news reporter from any major news outlet if they could describe the difference between the two, they would be able to? Or 90% of the general public for that matter. Its not like one title gives him more credibility than the other in the eyes of most, so I think its an odd thing to focus on.

Picking a couple of cases or prices isn't a real good indicator of the true market. KBB uses large numbers of actual sales combined with mileage and condition to provide a pretty good estimate for value of a given car, that data isn't yet in for EVs yet, IMHO. When I Google resale values for EV's, I see a lot of different results, including some pretty pessimistic outlooks. I'm really not focused on Teslas as much as the EV market in general, nor do I care about assumptions on what they might be in the future. There is not really a good historical database yet, as there is for gas cars, so the risk is certainly present.

I would not assume "the motor does not wear" in EVs. They certainly will wear, but it is also very possible that they may last a lot longer than ICEs. We'll see in 10 years when we have a lot of cars with a lot of miles on them under a lot of different conditions. Body resilience & condition is a large part of resale value as well.

Interestingly, the Nissan Leaf outsold the Tesla last year, but there is this desire to focus on Tesla as the game changer. I think your point is a very good and it is quite likely that a higher percentage of Leaf purchases are based more on practicality than Tesla purchases. A lot of Tesla buyers get them simply because they are really cool and unique cars.
