Consider price point implications.
Well, if SDVs take off as advocates espouse, the volume (plus Moore's Law) will make costs drop.
Volume maybe, but Moore's Law definitely not.

#472NTSB: • At 8 seconds prior to the crash, the Tesla was following a lead vehicle and was traveling about 65 mph. • At 7 seconds prior to the crash, the Tesla began a left steering movement while following a lead vehicle. • At 4 seconds prior to the crash, the Tesla was no longer following a lead vehicle. • At 3 seconds prior to the crash and up to the time of impact with the crash attenuator, the Tesla’s speed increas…
Shortly after the accident, a few other Tesla drivers reported similar behavior approaching that exit. But on the other hand, gores like that can also trick human drivers. Especially if tired, with poor visibility. In heavy rain or whiteout, I typically end up following taillights. But slowly.
Except that software doesn't get tired, and conditions were good. So even if that could trick human drivers those conditions weren't present so do not apply to the case at hand.

#473> During the 18-minute 55-second segment, the vehicle provided two visual alerts and one auditory alert for the driver to place his hands on the steering wheel. These alerts were made more than 15 minutes prior to the crash. Whoah. So there were NO alerts for 15 minutes prior to the crash. Compare this with Tesla's earlier statement: > The driver had received several visual and one audible hands-on warning earlier in…
Even the 'the driver’s hands were not detected on the wheel for six seconds prior to the collision' is suspect because it is known to be a pretty unreliable detection mechanism.
Besides, it doesn't matter: if the drivers hands were on the steering wheel they clearly weren't alert enough to hit the brakes or steer away from the impact so the point is entirely moot: autopilot was in full control of the car, whether the driver had their hands on the wheel or not to satisfy an alarm doesn't matter.

> I don't think a road like this would be possible in most of the EU. I've driven in almost all countries in the union and I'm sure that and worse is readily available in multiple EU countries. While it's true that the EU subsidizes a lot of road construction local conditions (materials quality, theft, sloppy contractors) have a huge impact on road and markings quality.
Hmm, "possible" was probably too strong of a word. Of course it's possible. However, I've driven a significant number of hours in Spain, Switzerland, Germany, UK, Ireland, Sweden, Denmark, Norway, Sweden, Finland, Estonia, and I wouldn't say that this kind of concrete divider is "readily available" as a normal part of a high-speed road, lacking the high-visibility markings I outlined in the post above, year after yea…
Try: Poland, Romania, Hungary, Bulgaria, Greece, Slovenia, Slowakia, Czech Republic. Those are also part of the EU and road quality there varies wildly from the countries you use as your examples.

It does not, in any way, imply that pharmaceutical companies would do a better job if left to their own devices and market pressure .
There's a lot of sunlight between letting pharma companies run rampant and having the FDA. One could imagine private non-profit testing and qualifications standards organizations along the lines of the underwriters laboratories
And who will manage all that testing? A government entity? Because that would bring us back to the original point.

This is pretty apples-to-oranges. You see things like this in a lot of less dense U.S. areas as well. But in the crash example, it's right in the middle of an interchange, with the lane needing to form and rise quickly. Additionally, the gently rising metal barriers aren't safe in many situations because of their ability to launch cars. That's why they've been replaced by crash attenuators and sand/water barrels. Unf…
Why are roads in the US so post-apocalyptic? Even your good example here looks horrible.
Hmm, perhaps something to do with there being more road miles in the US than in all of Europe combined?

> So what is the right way to handle these updates? Avoid doing them in the first place? It's not like bit rot is - or should be - a problem for cars. It's a problem specific to the Internet-connected software ecosystem, which a car shouldn't be a part of. So basically: develop software, test the shit out of it, then release. If you happen to find some critical problem later on that is fixable with software, by all m…
Tesla does test the shit out of it before they release a patch. The problem is that users expectations of the systems performance suddenly get out of sync with what the car is going to do. Part of me wonders if there should be a very quick, unskipable, animated, easy to understand explanation of the patch notes before you can drive when they make material changes to core driving functionality.
Or make certain critical updates only part of a physical recall, which provides notice to users that behavior will chance.

While using Autopilot (Big A), there should be a loud klaxon every 30 seconds followed by a notification "CHECK ROAD CONDITIONS" and "REMAIN ENGAGED WITH DRIVING" in the same urgent tone of an aircraft autopilot (small a) warning system. Tesla did make a mistake calling it Autopilot, but only because regular folk don't understand that aircraft autopilot is literally a heading, altitude, and speed, and will not make a…
I don't know why Tesla defenders keep repeating this FUD:
> Tesla did make a mistake calling it Autopilot, but only because regular folk don't understand that aircraft autopilot is literally a heading, altitude, and speed, and will not make any correction for fault. Aircraft autopilot will fly you straight into a mountain if one happens to be in the way.
Auto-TCAS and Auto-GCAS exist, and the public is aware of them: E.g. http://www.airbus.com/newsroom/press-releases/en/2009/08/eas.... http://aviationweek.com/air-combat-safety/auto-gcas-saves-un....

That is not accurate. In fact one of the key features of radar processing is to find objects in the clutter, usually by filtering on Doppler shifts. As far back as the 1970s helicopter-mounted radars like Saiga were able to detect power lines and vertical masts. That one could do so when moving up to 270 knots and weighed 53kg.
For radar detecting a power line against the sky is easy. Detecting a power line against a wall is not. The same radar set that worked these wonders while flying would have been absolutely useless for a ground based vehicle.
But a car's radar doesn't need to detect a power line against a wall; it only needs to reliably detect the wall...

So it should be possible to murder Tesla drivers by painting adversarial strips on the road?
