My take is simple. Multimillion dollar passenger Jets have Auto Pilot and Auto Land. They STILL CRASH from blips in those systems. Even with a Pilot and Co pilot. The problem is simple. Qualified Pilots get LAZY and trust the Auto systems too much. Then add weather problems. While the systems will probably be almost perfect in years to come, it will be just that, YEARS to come. With GAS and DIESEL on the road the problem is it is not safe. I would like to see a Auto system react to when a front tire blows. Doug

PS, I think a funny video would be 75% Auto Cars in rush hour freeway driving[emoticon]

He is guessing it is in autopilot simply because she has one hand on the wheel, but is only guessing. He doesn't like going 75, but is going 75 to stay with it while talking and looking into his camera to do his video, even raising both hands off the wheel at one point. He apparently speeds up to pull up beside the truck which implies he has increased his speed beyond 75. Not sure which one to be more concerned about.

The state has determined 75mph is a safe maximum speed.
I would be more concerned about following distance and proximity to other vehicles when changing lanes.

Watch at 1:42 seems closer than necessary and within 5 seconds the truck is braking. Seems odd for self driving.

In AZ, these trucks are allowed to operate in all five autonomous modes but they are geofenced based on the mode. Level 5 (with non CDL driver in seat) can only operate on I-10, I-8 and I-40 and within specific limited terminal areas. The ones in that video normally operates in Level 4 which is the same system UPS has been using on I-10 between Tucson and Phoenix. Arizona has been a test site for autonomous commercial vehicles since 2014 up to and including level 5 testing.

Because much of what is occurring is R&D testing, what you see (drivers hands on wheel) is not an indication of who is driving but may be a test of the steering wheel sensors or even hands to eye detection systems.

Also, since many of the trailers are not specifically designed to work with an autonomous vehicle, actions of the tractor portion will replicate on the trailer as normal. So if the tractor applies brakes to maintain a specific speed, the trailer's tail lights will reflect the braking action.

Do it all the time in my A. Set cruise control on, tie a bungy cord to the steering wheel, and go in the back to take a nap. So far so good!

Bungy cord, where did you learn about the bungy cord. The sales people did not say anything about using a bungy cord, and there is nothing in the information that came with the MH about a bungy cord either.

Bungee cords are not designed to keep your steering wheel straight while you nap, always use a proper ratchet strap.

40' diesel with steer safe and IFS! Works great as far as I can tell. Most of the time I'm asleep though.

75 is an issue how? Lot of the west has 75 speed limits and some are 80. My name was on the side and time is money. The posted speed is considered the safe speed, if there is a slow down or bad weather it's up to the driver to know whats safe, that's what they are paid for, to get the freight to it's destination safely.

Can't wait to see if these self drivers exceed the CA 55 speed limit.
