Only if you are close to the road while it is currently running in the direction you want. Seems like a difficult thing to abuse.

No, that just keeps the car moving. Not in any particular direction.

No. I’d go so far as to say this doesn’t work at all. That sounds dangerous as hell and would be a menace on the road.

Only if you want to look like a drunk driver. I wish it worked like that, but all it does is jerk back to the center of the lane about half the time and then complain that "steering is required".

If you have a force pushing it onto the road wouldn't that suffice to make it steerable?

Ya you can do that, but then it feels like dangerous. When it gets like that I usually just shut it off and control distance myself (and "cough" adjust it to dissuade swerving and then back off for safety).

I think it only uses the car in front for speed corrections. It will stay in the lane it's in.

This is a feature that should only be used for off-roading. Off roads, it is extremely useful to be able to make small-radius turns.

I wouldn't say it prevents you from doing much of anything. The car will still speed however you want it to, just not with the machine in control.

Some places have laws requiring you to move the vehicle off the road if it steerable. There has to be some way to move the vehicle manually.

It will to a certain extent. It's a powerful tug on the wheel and will follow the curve all the way through. You still need to keep your hands on the wheel or it yells at you.

Yes, just make sure to take corners wider than one would in a car.

Anecdotally, this is precisely my experience. It'll start the engine, but you have to navigate the course.

I just like to feel in control of machine, here it wouldn't be possible.

Besides - the more direct control is the more predictable behaviour of this vehicle can be.

I don't think every possible route between 2 points will be possible even using these vehicles. So steering this will probably look more like RTS - I pick control points, unit chooses the path.

This can cause some pain.


Would this not apply a force against the direction of travel, thus making the car expend more energy than gained in order to maintain speed?

Correct me if I am wrong.


It's hard to actually drive straight in any direction unless you have a tank but if you could that is probably pretty accurate.

Waymo and Cruise both have remote operators who can remotely unstuck cars.

AFAIK they can’t drive the cars directly, but the they can give override commands, reset software, or make the car follow a manually set path. They probably can’t make it reverse at full tilt though ;)

Directly driving cars is considered very sketchy as you could have network latency spikes or dropouts at any time.

That said, it’s possible the cone still prevents the car from moving at all because either:

a. It creates a large enough sensor blockage to be deemed ‘unsafe’ for any movement

Or b. The car thinks its been in a collision, or thinks it can’t move without ‘colliding’ with the cone further.


i'm not talking about parallel backing into a spot, i'm talking about reversing down the street a few hundred feet.

Yes, but only because in the general case, the actions are very limited by the controls of a car.

Steering wheel, two pedals, that's only three axes of possible inputs.


yes. a bug in the programm and it takes insane measures (i.e. breaking and steering hard right), salvaging that situation is impossible at higher speeds. its doubtful that a beginner would do such a thing, and even the attempt would take longer, giving the supervisor more time to interfere.
