I have had a computer since the time when you booted them with discs.  In that 30 plus years, I doubt that this simple device spent more than one or two percent of its life without a glitch, hardware issue, bug, virus, or something unexplained that would from time to time piss me off.  Only one other trapping of modern society is able to cause creative vulgarity to flow from my lips, and that would be my cars.  Brilliant.  Lets have a marriage, pop out a baby, and let it have full control of my safety and well being. 

I'll concede that driving is more often a pain in the ass than pleasure.  So is fatherhood, and I wouldn't have it any other way. Ceding total control to electronics is just not something I am comfortable with.  I can read maps and generally know when my GPS is full of bovine scat.  It happens way too much.  Not a fan.  However, there is also a large percentage of the populace that has no ability to drive safely, and for them, automation is the best option available (besides mulching the lot of 'em).

This tech isn't going to be the same as trying to play Space Taxi on your VIC 20!  (kidding)

The opinions on this post are pretty interesting.  This tech is going to make the roads safer, no question.  But some don't/won't trust it.  That's not surprising though--it's human nature to feel more comfortable when you are in control of your own fate.  When my kids take their first trip to Mars (don't laugh), I want tech flying the rocket--not some dude holding a joy stick.

I think the reservations expressed about losing the cultural impact of driving is something we'll see more and more.  The younger generations won't share the nostalgia, but the transition might be tough for our generations.  But that happens with most tech.  Remember trying to teach you parents how to use a VCR?  People used to complain about the negative impacts telephones would have on the telegraph.

The impact on jobs is going to be a tough one to get through.

But love it or hate it, you have to admit the tech and progress are impressive.  Telsa and others have been releasing lower levels of self-driving cars for a while now, but those two demos posted above really knocked it home for me how close it is to hitting a tipping point.

With my shoulder, I need that board to be self-surfing!   Maiden session will be March 10!

America is in love with it's cars, for many very good reasons.

Hey Creek, one piece of good news is Google is out of making cars.  No more bubble mobiles.  We might get some of those rocket cars after all (though probably powered by electrons).

Actually, they spun it out. the company is now called Waymo. www.waymo.com  So you can still get that bubble surfmobile you want Creek. No steering wheel at all.

The world's quickest car is now a Tesla 4 door. 2.28 seconds 0-60 for the P100D. Ludicrous indeed. Front page of today's WSJ.

I thought the Porsche 918 Spyder (2017 model) can go from 0-60 mph in 2.20 seconds and if it can then that beats the Tesla.

I wonder why the WSJ didn't mention that. They say the La Ferrari was #1, now #2.

The article also gets another thing wrong--they claim the advantage of electric motors is that they have instant torque. The actual advantage is that they are thermodynamically efficient and don't need to reject at least 53 percent of the power as heat (more like 60). Instant torque is certainly an element, but it's more important that you can get 400 horsepower from a motor a little bigger than a coffee can.

And they misunderstand the battery heating issue. If you design the system for normal operation you need to reject about 10 percent of the power being used as heat--both from the motor and the battery. Building the car for maximum aero efficiency means tiny radiators with managed airflow, not a garage door at the front of the car. The radiator on my new diesel truck looks like it could cool a nuclear reactor. A La Ferrari has five radiators.

So yeah, maybe they got it wrong and the five-passenger luxury grocery getter slots between a 918 and a La Ferrari.

But hey, it's a newspaper.

"Autopilot is getting better all the time, but it is not perfect and still requires the driver to remain alert, the company said.

Based on vid footage of near misses -> maybe best that the bugs are worked out before taking your eyes off the road.  But for the early adopters - you can be first with this right now.  Very unfortunate software error.  The vid below was from the driver showing the system in action.

"You could be asleep the whole time - uhmm - and do so very safely

"If there is an accident the driver of the car is still liable.  So we are very clearly saying this is not a case of abdicating responsibility"

Elon Musk - check out his vid here ->

https://www.theguardian.com/technology/2015/oct/21/tesla-autopilot-goes-wrong-videos

The more early adopters the better.  Maybe after the real danger bugs have been worked out - might consider this.  But till then -> you first.  We need a lot of beta testers first though.  And a few more real life accidents vs speculation.  ;)

Missing that truck in the vid was way too close of a call.

A driver that has plenty of skill and demonstrated expertise on any roadway should be much better able to cope with the myriad of emergency situations that arise second to second.  We do that all the time.  Defensive driving to the max but know when to accelerate and go with the flow or separate.  Claims free max discount is key.  Apparently most on the roadways in BC have max discount.  Driving on a track to practice evasive maneuvers is important as well.  You need to know the handling limits of your vehicle in emergency situations - and should practice in adverse conditions to get better.

Speculating that this way of hands off driving is safe -> is off base.  It may be safer for many but looks to be unsafe for others more skilled than a computer program.  This tech is in its infancy and has a very long way to go.  But do please buy one of these and add to the millions of miles using this automation.  It needs all those millions of miles and more -> to work out the bugs.  This is not just a home computer that has a little glitch that you can debug easily and safely.  It puts your life at risk and your family at risk and others at risk.  Certainly buy one though and use it now.  Put it through its paces.  Tesla needs a lot of beta testers and accidents to sort through all the crap algorithms that remain.

Just seems so risky to put so much faith in early adopter beta software.  But hey - everyone makes their own choice on what they trust and not trust.  So do it.  Buy one and put it into auto mode.  And doze off - drink some wine - play cards or chess - or check your email going 70.  You should hopefully arrive at your destination fresh as a daisy.  Or not.
