There are suggestions that the LIDAR (LAser Detection And Ranging) technology
that the Google car uses may have been more effective in this situation than
mobileye used by Tesla. I read elsewhere that because LIDAR needs to be mounted
on the car there may have been a “vanity” issue in using it instead of mobileye
although Elon Musk simply seems to prefer mobileye (I have to say I would not
put a “vanity” reason out of the question as much as I admire Elon and that
would be pretty damning). I’d imagine V2V (vehicle-to-vehicle) communications
would improve autopilot safety significantly. Time will tell.

Google car with LIDAR. It is enormous – I think I do understand the vanity
issue.

Well, that is the suggestion that Tesla is trying to implant but I just don't
buy it. You just don't not see a vehicle because it happens to be the same
colour as the sky behind it. Would you or anyone drive into a white truck on a
bright day? Or a sky-blue truck on a clear day, or a black van at night, or a
grey station wagon on a cloudy day? A red, orange and mauve Kombi just after
sunset?
Personally I'm in favour of driverless cars and I think that eventually they
will be much safer than human driven cars to the overall great benefit of
society. But if Tesla is seriously saying that this is where the technology is
at: a white trailer might be invisible on a clear day... wow, they're some way
off being ready to let these things on the road.

"IMO a human driver would have noticed a tractor-trailer looming up in the
windscreen and tried to avoid it. "
Apparently, the trailer of the semi-trailer was bright white, and the day was
bright and sunny. So some people think that the auto-pilot and the driver did
not see the trailer.
In Australia for many years now, large trucks have a rear bumper bar
arrangement that stops a car from running under it. It looks like a bull bar
at the back and is painted white.
Some also have a side bar arrangement that stops cars running under the truck
or its trailer from the side.
