Which document describes where it "misclassified Elaine Herzberg so many times"?

Here is a revised link [1] to the full report. Table 1, on Page 10 shows a summary. [1] https://dms.ntsb.gov/pubdms/search/document.cfm?docID=477717...

Wow, that was interesting.

At every change of identification of an object it becomes "static" again. That seems very stupid if you've already estimated the path of an object.

The human driver didn't do too badly I think. The auditory alert only came at -0.2s until impact, and they braked at 0.7s after impact.

From relaxing and playing with your phone to braking in only 0.9 seconds.

Of course they were supposed to be paying attention, but I fully understand how it would be difficult to pay attention for hours without having to do anything, then suddenly be expected to react immediately. That's the most dangerous thing about these half-driving cars.

The algorithm I apply is actually pretty simple: First at the intersection goes first. So you, individually, should let everyone who was there when you arrived go before you, but you should go before everyone who arrived after you. It gets messy when people try to be polite or don't understand the rules correctly, but otherwise it's pretty easy. It might depend on your jurisdiction, though.

My algorithm is so much more complicated than yours. In my area you get rear-ended if you were going straight and you didn't go when someone coming from the opposite direction but also going straight went (your algorithm doesn't allow that). Assuming cars are already at the intersection, I wait until each of them goes and then take my turn, unless it's someone's turn who wouldn't cause a conflict with me and nobody e…

People in your area get rear ended while stopped at a 4-way stop?

> Tesla has cleary won the race.. But Waymo is pilot-testing autonomous taxis and Teslas have a "greater than zero chance" of making it to your destination without intervention.

First Mover Advantage is still pretty important though. Tesla is selling cards today, Waymo is not. Tesla's cars are good-enough for most of the buyers so Waymo's technical superiority has to bs much much better warrant the attention and change in public perspective. On very important thing is tesla has established that your will get better with software updates over time. Other cars have nice adaptive cruise control…

>Tesla is selling cards today, Waymo is not.

Tesla sells cars for which FSD doesn't exist, Waymo is using FSD on cars they don't build.

The business models are different. Why is the natural assumption that everyone will own their FSD car?

Plus Tesla still does not report disengagements to the CA dmv, right? It seems so strange to me that their HQ is there and they do not report any testing there.

Why is that strange? Does Tesla strike you as conventional?

It strikes me as evasive.

It diminishes the comparison when just the lidar for a waymo car costs more than the entire tesla vehicle. So, not only can you afford a tesla vehicle, you can go out and buy one today.

According to [1] Waymo produces its own lidars. In 2017 it costed $7500 without being mass produced. Edit: wording. [1] https://www.theverge.com/2017/1/8/14206084/google-waymo-self...

All the Waymo vans I've seen have had multiple lidar sensors, I think 4?

Great point.

Tesla exists for people who want to own/drive their cars with cool tech and the dream of FSD down the line via a magical update

Waymo's launched Waymo One as a taxi service but it's only available in one region. My understanding has been that they want to buy a fleet of cars, outfit them with their FSD tech for a taxi service? (So competing with Ridesharing services as an autonomous alternative)

There is certainly plenty of room in the market for people both models

What are these levels you are referring to? We drive just fine with two cameras.

And two actuators in every eye ball and two big actuators between the head and the main body.

Because our field of view stinks.

If the person is supposed to go but doesn't, then sometimes.
