The tremendous personal arrogance of Elon Musk, and the blissful disregard of those who would rather agree than question him, will probably ruin the industry for many others to come. Eventually enough people will have died in frankly ridiculous circumstances that trust will be lost.

Re: Why emergency braking systems sometimes hit parked cars and lane dividers
#192Autopilot would have worked fine if the lane markings were properly painted. No one will blame Caltrans terrible maintenance of 101. As I am writing this, NB 101 near Oregon Expressway has been under construction for over two years with no painted lane markings (and the lanes suddenly become super narrow), leading to merge hell and probably at least 3-4 fender benders a week. The Tesla GUI shows you whether or not it…
You're presuming that in these fatalities that the driver's eyes weren't on the road. What if the autopilot executed a maneuver that attentive drivers couldn't recover from in time?
Such as swerving unexpectedly into a concrete barrier which was not obstructing the road, and accelerating.

People smell better in Europe? When people trot out their arguments against public transportation they always refer to the inefficiencies and completely ignore the human element. No one wants to be crammed in a small space with a bunch of strangers every day.
Possibly not showering is just more socially acceptable in the US or something? I dunno, I see this a lot on these discussions, but it’d be fairly rare that I encounter a notably smelly person on public transport here. Being on a bus/tram/train with strangers never really bothered me, to be honest. When I walk down the street or onto a shop, I’m also surrounded by strangers; what’s the issue?
My experience (mostly BART & SF Muni Metro) is that “smelly person” is a euphemism for homeless person.

That's strange. As one of most popular "crash management" systems on the market, one installed on Volvos is quite good at this, to the extend they put it's test video into their commercials. A sponsored article?
https://support.volvocars.com/hk/cars/Pages/owners-manual.as... "WARNING "When the adaptive cruise control is following another vehicle at speeds in excess ofca 30 km/h (20 mph) and the target is changed from a moving vehicle to a stationary vehicle, the adaptive cruise control will ignore the stationary vehicle and instead select the stored speed. "The driver must then intervene him/herself and brake."
Wow, that is some really unclear and weaselly wording. Do I understand correctly that it means "This system might decide to 'follow' a stopped car and crash into it, and then we'll say it's your fault"?

Waymo seems to be doing just fine on their own. I'm not sure they feel they need any partnership. They just ordered some 30,000-ish cars, so it would seem they're entering the mass-production phase.
There's active disdain (or at least snide jokes) among the senior Waymo engineers for the approach to autonomous driving taken by Tesla. I can't see a partnership in the cards, probably ever. Source: used to work there
How would the engineers at Waymo know Tesla's trade-secret approach beyond the physical hardware ? Tesla is the only major player in the race to autonomous cars that has no patent. Waymo has 145.[1]

#196This idea of refusing to use a 3d imaging system because it's theoretically possible without is sort of bogus.
No one refuses to use GPS because it's possible to use a map or sextant like humans can. No one refuses to use radar because you might be able to point at a plane with your eyes.
Tesla should invest in improved lidar or imaging radar, rather than hoping they can come up with a neural network to solve all their problems from visual images.

don't mind operating at a loss That's ridiculous, they might base this on some other benifit such as type of owner, but the industry is not just going to subsidize 100,000+ plus people. I am not saying it's fool proof, but your bias is showing.
I mean Tesla doesn't mind operating at a loss, as they are trying to push autopilot to the market. By the way, the black box recorder in a Tesla might also contribute to the discount given by insurers.
Tesla operating at a loss would have zero impact on insurance companies and they in no way are talking on that burden.

#198And it also creates a danger that the car behind won't stop in time, leading to a rear-end collision.
Inattentive tailgaters shouldn't be accommodated. Sure, their problem becomes your problem when you brake hard, but I'd much rather be rear-ended (with head rests and the whole rear of the car as a crumple zone) than plow head on into a stationary object at high speed.

I'm betting a bunch of them own Tesla's (status symbols). You can tell a lot about a system just by using it and testing it.
Re: Why emergency braking systems sometimes hit parked cars and lane dividers
#200A common situation, certainly on British motorways in relatively heavy traffic, is to be tooling along at 70mph, and then have to come to a halt - or drop to 20mph - fairly abruptly due to waves of slow moving traffic that move backwards along the carriageway. I wonder how well such systems would handle that kind of situation, where obstacles might not be stationary, but the speed difference is large?
It depends on the detector used. Radar in particular is bad for stationary obstacles because it can't separate reflections from the ground from a stationary obstacle. Moving objects are no problem because their radar reflections gets doppler-shifted and can then be separated the ground clutter.
Thanks - makes perfect sense.
