> Want safety? How about a Tesla that is electronically incapable of speeding. That would be unsafe in many situations. If the flow of traffic is substantially above the speed limit--which it often is--being unable to match it increases the risk of accident. This is known as the Solomon curve [1]. [1] https://en.wikipedia.org/wiki/Solomon_curve

> Subsequent research suggests significant biases in the Solomon study, which may cast doubt on its findings With the logic presented in the theoretical foundation section, it seems that the safer move would actually be slow down and match the speed of all the trucks and other large vehicles... which won't happen. Matching speed sounds great, except there are always people willing to go faster and faster. In my state…

To address your last paragraph, everyone going 85-90 is less safe than everyone going 70-75, you are correct.

However, you individually going 70-75 when everyone else is going 85-90 is less safe than you going 85-90 like everyone else in the exact same situation.

>there are always people willing to go faster and faster

That’s why no one says “go as fast as the fastest vehicle you see”, it is “go with the general speed of traffic”. That’s an exercise for human judgement to figure that one out, which is why imo it isn’t a smart idea to have the car automatically lock you out of overriding the speed limit.

> Illegal (no signal) lane change results in a steering wheel shaker (and optional audio alert). To be clear, tying the warning to the signal isn't about preventing unsignaled lane changes, it's gauging driver intent (i.e. is he asleep and drifting or just trying to change lanes). It's just gravy that it will train bad drivers to use their signals properly.

Is a lane change without signal always illegal? I know that it almost certainly make you liable for any resulting accident, but I'm not sure that it is universally illegal.

This is technically true in Ontario (TIL).

> 142 (1) The driver or operator of a vehicle upon a highway before turning (...) from one lane for traffic to another lane for traffic (...) shall first see that the movement can be made in safety, and if the operation of any other vehicle may be affected by the movement shall give a signal plainly visible to the driver or operator of the other vehicle of the intention to make the movement. R.S.O. 1990, c. H.8, s. 142 (1).

That said there's zero cost to doing so regardless of whether other drivers are affected.

Usually, it makes you liable because it is illegal. CA law for instance reqires signalling 100ft before a lane change or turn.

I’d be curious if there are studies out there on how to do automated assists in machines that require vigilance that don’t have this problem.

Both airplanes and trains have automated “assist.” At least in the case of WMATA they give up on automatic train control after a fatal crash.

This is a misrepresentation of the dumpster fire that was the WMATA train situation. Yes, the fatal crash was the last straw, but the root problem was not the automation system but rather the complete lack of maintenance that led to its inability to work properly. Congress refusing to fund maintenance and then falling behind 10-15 years on it lead to all kinds of systems failing. The fatal fire in the blue line tunnel under the river occurred with a human at the controls, but we’re similarly not blaming that incident on the perils of human operation.

Why isn’t defeating the self-driving attention controls a crime like reckless driving? Isn’t that the obvious solution?

It almost certainly is, at least when combined with the intentional inattention that follows. Making it a crime isn't an "obvious solution" to actually make it not happen. Drunk driving is a crime and yet people keep doing it. Same with texting and driving.

The problem is determining who is liable for damages, not prevention. Shifting the liability for willfully disabling a safety control puts them on notice.

Prevention as a goal is how we end up with dystopia.

I recall a particular incident where Waymo was marketing their car being able to drive a blind man to a drive-thru, way before the thing could safely drive more than a mile on it's own. My understanding is that in 2021, it still can't navigate parking lots (which would preclude using it for drive-thrus). Later, they were talking about how sophisticated their technology was: It can detect the hand signals of someone d…

The workers doing road repairs in my neighborhood don't even use handheld stop signs. Just vague and confusing gestures.

I think in those cases a Waymo vehicle would probably require remote assistance. It's a really difficult scenario for a computer to make sense of.

Predictable outcome of a sensing system fully based on deep learning. Rare unusual situations don't have enough training data and lead to unpredictable output. I still think that Tesla's approach is the right one, I just think they need to gather more data before letting this product be used in the wild unsupervised.

Current TACC/auto-steer doesn’t use deep learning except on the newest Model 3/Y vehicles with “TeslaVision”. All cars with radar use the radar and radar only to determine if they should stop for the following car.

How does TeslaVision work with stationary objects at night? Like say a big ass truck with its lights off? Do you just pray the vision system recognizes “something” is there? I know they want to pursue a pure-vision system with no radar input, but it seems like there will be some crazy low light / low visibility edge cases you’d have to deal with.

> Also, these cars know the speed limits for the road Does it always get this correct, or does it sometimes read a 30mph sign on a side road and then slow the car on the motorway down to that speed?

I'm not sure how the cars know the speed limit. Maybe someone else knows? My guess is combo of GPS/camera to position correctly on road and the lookup of known speed limit data. Perhaps it reads signs though?

My car shows the speed limit of roads it knows. It uses GPS and stored limits. It also doesn't know the limits of non-major roads and doesn't attempt to show a limit then. My car is a 2013, and I've not paid the $$ to update the maps in that time (seriously, they want $200-$400 to update the maps).

Since I bought my car, Illinois (where I live) has raised the maximum limit on interstates by 10 MPH. My car doesn't know about it. If my car limited me to what it thought the limit was, I'd probably be driving 20 MPH slower than prevailing traffic, a decidedly unsafe situation.

> We have empirical data showing how safe actual level 2 self driving cars are in practice. Do we? Where does that come from? The data Tesla provides is hopelessly non-representative because it makes the assumption that the safety of any given road is independent of whether a driver chooses to switch on the system there.

Only overall numbers actually mater here, if self driving is off then that’s just the default risk from human driving in those conditions. Talk to your insurance company, they can give you a break down by make, model, and trim levels.

I am pretty sure that if I call Geico they will not provide me with those data. Am I wrong?
