Does autopilot give any sort of warning when it drops out ? It seems
that it should do something that grabs you attention instantly, e.g.
vibrate the steering wheel or even a mild shock.

Thanks Bill.
Folks, We could argue the details back & forth but fundamentally a computer
dropping out during a critical life function is a *fatal flaw* in
engineering. Sure the folks that ran into trees during self driving should
have been more attentive, but when you pay $10K extra for a "feature" and
start getting used to it, driving daily to work for a year (on a curvy road)
and nothing happens, start getting less vigilant - then one bright sunny
Tuesday morning, surprise! Into a tree.
I use the self driving mode on *straight* highways "auto pilot" (when you
don't pay the extra $10K) - it's nice, takes the fatigue out of long trips
*but* I've had the computer drop out several times going to Florida and up
to Pennsylvania and thought nothing of it, just bop twice the right stick on
the column and it starts back again. I almost bought the extra $10K full
self driving package for my handicapped wife *but* after my friends
accidents and seeing it drop out on me, I realized it was a *bad* idea.
Best Regards,
Mark

Michael -
??? How, exactly, would Mark be able to provide "factual data" on this
incident?? If you think about it, how would _anyone_ be able to, since the
device that could record the incident data was off-line at the time it
happened and this was the root cause of the incident? Mark speculated that
it was quite possible that other similar "glitches" have caused other
similar unrecorded incidents.
??? I have known Mark for more than 20 years and have found him utterly
truthful and reliable. If he says it happened, I completely believe it
happened.
??? Also, I can envision how this could easily happen and how it would
completely escape the notice of Tesla. On commercial airplanes, they have
two (2) separate flight computers, using two different brand CPUs, using two
completely "firewalled" separate teams of code developers for their flight
computers. The two systems continuously monitor each other for faults and
warn the pilots when they see any divergence in flight control between the
computers. There are two _other_ separate systems recording flight data as
well. They do this because peoples lives depend on these systems working
perfectly and continuously. There is no similar multiple redundancy in
Tesla. _YOU_ are the redundancy that they are depending on to take over if
there is a computer glitch.

Mark, Can you show me where this anecdotal information might be
gathered as factual data? I have become very wary of information that
is not attributed to some source that I can trust. No offence intended.

Tesla should just drop the whole self driving thing and just focus on
a great electric car. My Tesla Y was the only EV I could find with
towing capacity for my H20 ski boat and an excellent nationwide charging
network.
The problem with self driving is when the computer gets a glitch, it
drops out and the vehicle goes straight, usually into a tree on a
curvy road (happened to my friend last year and previous year to his
wife in a Tesla3). Of course when the computer drops out it doesn?t
record the crash as a self driving error. How convenient for Tesla.
The actual crash rate is much higher than recorded.
