Not really no.

While I understand your position and experience mine has been 
significantly different. Just a few years ago I was heading out to 
Clive, IA. I dutifully updated my Garmin. Before leaving my yard I tried 
to set the destination. According to Garmin, Clive, IA (a suburb of Des 
Moines) did not exist. Could not find it by zipcode or name. Could not 
even find the hotel I was staying at. I had to drive to Des Moines and 
"wing it." I have a 16Gig SSD in there and Garmin is pretty good about 
letting you know when an update won't fit.

When I got to Clive and found the hotel I saw the water tower for Clive 
which had to be at least 60 years old. The hotel seemed even older. 
Adding insult to injury the following morning when I was about to pull 
out of the parking lot Garmin actually showed me the street I was on.

Driving out to Oregon over one Thanksgiving I got to a spot in the 
mountains where it seemed only the AM radio got signals. No cell 
service. Even the Satellite stuff didn't seem to work. I heard the 
Interstate was closed due to the snow and a "mega load" being stuck on a 
bridge and unable to climb the next icy rise. I found out the Interstate 
was now closed via the big orange gate across it as I came over a rise.

Driving to Chicago the evening before meeting with clients I have 
numerous times gotten to enjoy Garmin (my model also receives the FM 
signals) trying to route me up a ramp which was subject to nightly 
rolling closures as workers stripe/resurface. Few things more enjoyable 
than encountering that late at night while having the nav system 
continually try to re-route you back to said closed ramp.

Where this flies apart is the innocent sounding phrase "operational 
area." The once a year family road trip to visit some part of America 
(or insert country here if your culture has annual road trips) now 
defines a new operational area which will require an update right when 
all connective services have disappeared.

Yeah . . . GM isn't going to give you a steering wheel.

While I applaud them and hope the laws change so anyone with one of 
these vehicles without a steering wheel can get falling down drunk in a 
bar, pour themselves into the front seat and slur "Home Jeeves" without 
getting a DUI, I also live in mortal fear of such a system built by the 
lowest cost labor GM can find. The billing rates I hear from the 
recruiters reaching out to me about Qt contracts to work on this stuff 
in Michigan at the Big 3 locations are _NOT_ bringing in seasoned pros.

Oh. Poke around on the Web. There is a passable video from Microsoft 
automotive division (the division without any customers because Ford 
fired them over the shit job they did on Sync). It talks about the 
volume of sensor readings they are currently getting per second and 
stuffing into an on-board SQL server. That is just straight forward 
motion without navigation. They haven't even gotten to the life 
threatening "fun" of wind gusts. Message off-list and I can tell you 
about the "fun" of driving an 18-wheeler through the mountains during 
high summer winds having only 20,000 pounds in the box. So far none of 
the autonomous systems I've read about (not that I've read about all of 
them) are dealing with crosswinds. With a little bitty low slung car you 
don't have to worry about it. With an SUV, mini or tall van it's a 
serious concern. It was a real issue for the Buick Rendezvous I once owned.

All wheel drive was great but a tall, light vehicle like that made it a 
real challenge when driving in gusty wind even here in the flat Midwest.

I couldn't remember the highway number for the one which cuts through 
the mountains from Idaho to Oregon. There's supposed to be a little 
2-lane the yocals use when the Interstate is closed.

Sorry, Thunderbird wasn't set up for newsgroups. You will have to 
forward to gmane.comp.lib.qt.user
