I've always speculated it was just something that needed to be
reprogrammed. It's not a safety issue per say.. It just aggravates
people when they are on the highway. Myself, I think most of the
problem is there is likely too much assist at highway speeds, and
it needs to be toned down a bit.
On a normal variable assist steering, there should be a good
amount of assist at slow speeds, but very little if any at highway
speeds. At speed, you want to mimic the feel of a non assisted
rack and pinion.
I've always felt they must be running too much assist at speed
if it feels squirrely assuming the alignment is right.
It's nothing that is dangerous. It's not like the steering is going
to unhook and let you smash a guard rail.. :/ Good grief....

you should be able to recover the last 30 seconds of data from the
engine computer - that should tell you speed, throttle position, etc.
and whether throttle position stayed fixed. but even that doesn't
confirm with certainty - maybe the guy was having a heart attack and had
his foot pressed down in pain.

Electric windows/power windows, electric door locks, some vehicles have
electric/electronic doors and locks, electric trunks, (boots, in Brit
speak) power steering, power brakes, electric/electronic power
everything.Both of my Dodge vans have power steering and power brakes.I
wish they didn't have power steering.I can easily do OK with old style
factory installed manual/non power steering.Brakes too.

has more than mastered!

Now why can't they do that for the MASSES?

It's a difficult angle to explain, but pretty there's an invisible
line(like the earth's axis) around which a tire rotates as the wheel
is turned. Facing the car dead on, this steering axis is inclined so
that it angles in at the top(toward the middle of the car). This is
not to be confused with camber, which is the tilt of the TIRE itself
in(negative camber) or out(positive).

The past 20 years it's been called Steering-Axis-Inclination. Some
truckers and old-timers still call it Kingpin.

It's function is to create lift as you steer the wheels away from a
dead-ahead. The wheels want to go down into the ground - which is
impossible - so the nose lifts, just perceptibly, as you turn the
car's wheels. When you let go the steering wheel, or let it slide
through your hands, the car's weight forces the wheels back to a dead-
ahead(in an ideal world!). This is the same counterweight you feel
when you turn the steering wheel to make a turn -either in a no-PS or
a car with variable-PS and you're at moderate to high speeds.

That is the exact feeling - that communication between the steering/
suspension & the road - most of us "luddites" are afraid to lose
during the fly-by-wire transition.
