True, but those arn't part of the engine ECU.

Shame they pinned everything on machine vision without radar and/or lidar 
backup and cost a number of - admittedly idiots - their lives.

The big question - vital, but probably impossible to answer - is how 
many crashes or fatalities would there have been /without/ the automatic 
systems?  People have been crashing cars and killing themselves and 
others for as long as cars have existed (longer, if you include wagons 
and carts).

Driving aids are not perfect, and they get things wrong sometimes.  But 
maybe in the big picture (statistics, not individual cases) they are 
still a win.

The problem is if you market a driver aid as "autopilot" then people get the
wrong idea and stop paying attention with the inevitable results especially
if the car "vision" is more falible than human vision in certain circumstances.
Other car companies call it Lane Assist or similar which makes it pretty clear 
its not 100% autonomous.

Yes, I can see that as a problem - if the marketing or naming makes 
people think it is significantly more automatic and reliable than it 
actually is.  I am not a Tesla driver, nor have I paid any attention to 
their marketing, so I can't really comment here.

I think it was a Google member who said about their self-driving car 
project: "If we succeed to reduce the number of yearly deaths in car 
accidents from 300 per year (number of The Netherlands) to 3 per year, 
then we will not receive 297 grateful letters per year from happy people 
that are still alive, but we will be sued for those remaining deaths.".

Yes.  No matter how hard you try to show statistics, or calculate

For some damn reason this is reminding me of the lyrics of a song (still 
alive) from Portal 2:

Some people do not seem to care if some people die, as along as the 
science gets done.

This article says that the new F-150 in 2016 has 150 million lines of C 
code.
    https://www.greencarcongress.com/2016/05/20160505-ford.html

"Software plays a growing role in new vehicles as demonstrated by the 
all-new F-150 that features more than 150 million lines of code, whereas 
a typical smartphone operating system has approximately 12 million 
lines. Engineers are capitalizing on software to deliver precise control 
over aspects of vehicle performance such as engine and transmission 
calibration to improve fuel economy and for the connectivity experience 
by giving customers hands-free access to their smartphones through SYNC 3."

Bill Ford gave a TED talk recently where he said that the average Ford 
vehicle has over 100 cpus on the EMS and daughter boards in it.

This inforgraphic claims that the average car has 100 million lines of 
code which blows my mind:

Yet still does single digit mpg around town. If they really wanted to save fuel 
they'd build it out of aluminium and literally save a ton of weight but that
wouldn't get the Kool Kids on board.

Ie there'll be a whole heap of faults and trouble awaiting the 3rd or 4th
owner 10 or 20 years down the line and it'll probably be uneconomic to repair
if too many modules fail.

Quite ridiculous really compared to some of the other systems especially given
most of it is in the bloated ICE which many people don't use anyway because
they just pair their phone and use that instead.

Why do car companies design the interface of cars for teenagers these days
when the people buying them new are are usually 20+ years older? One of lifes
mysteries.

They've been building the F150 out of Aluminum/Aluminium since 2015.

...

Those single digit mpg days are way past for F-150s.  My 2019 F-150 4x4 
3.5L dual turbo V6 with the 4 inch lift kit gets 16 - 17 mpg around 
town, 20 mpg at 70 mph, and 18 mpg at 80 mph (it is a brick after all). 
I just replaced my AGM battery so my start-stop system started working 
again so I am getting 17 mpg on this tank so far.

And my cab and bed are made out of aluminum.  I know this for a fact 
from throwing stuff in the bed and scratching the bed protector layer off.

20mpg in 2022? BFD. My 14 year old tired diesel can do 35mpg at that speed 
(admittedly UK gallons so probably ~ 30-32 US). Modern cars can do much better.

Though I suppose it begs the question of why americans feel the need to drive
around in absurdly large utility vehicles. Insecurity perhaps or maybe posing. 
But thats an argument for another newsgroup.

Something that perhaps 15% of non-commercial pickup truck owners actually do.

Towing a boat up and down to Lake Tahoe from Carson City, one needs a 
vehicle than can do it.

That covers about 0.005% of all large pickup drivers., but doesn't answer
the question posed above.  That stretch of Highway 50 isn't typical,
even in california or nevada (hopefully your're not taking 207).

I drive that stretch of 50 annually during my labor day Yosemite-
Lee Vining/Mono Lake-Tahoe journey (although every couple years, I'll
take 89 or 207 from 395 just for a change of scenery).
