Safety Score

[follow.johnny]

I've been driving exclusively on AP on the highway and I've been docked for aggressive turning on 2 of my five trips. Was at 100% yesterday but now I'm down to 96% because of alleged 9.6% aggressive turning. Makes no sense. I'm driving on the interstate with AP on at 5 over the speed limit. No way I'm pulling > 0.4 G's anywhere on that trip.

I've heard other owners say it was because of when they were merging onto the freeway (which they were driving manually) that dinged them for the aggressive turning. Try turning on AP (and navigate on AP) once you're about to get onto the freeway.

That is a joke, right ?

Yes, it is, but it's a long-standing one in the auto safety field. In fact, I misremembered the numbers:

93% of Drivers Consider Themselves Above Average. Are You Above Average? - Cheap Car Insurance

To make it a little clearer, only half of a group can be better than average at something, while the other half must be worse than average; and anyone

Phantom forward Collision Warning from a car that was turning right into a driveway and was significantly ahead of me (and successfully completed the turn without me even having to slow down) knocked my score down 4 points. Which is a significant amount according to this tweet

That is not a "Phantom" forward collision warning, that is a poor situational awareness by the software. I have a street on my way home that used to get that warning a couple times a week. Now with the scoring system I know it will happen so I go really slow behind the turning car until it has left the field of view.

Similar to how when you are on autopilot and a car enters a turn lane next to you and slows down your car goes extremely slow until the car is fully clear of the lane lines.

I have adjusted my driving according to Tesla's software this week.

My guess is the 'Early collision warning" setting configuration cost me some points yesterday (I thought I was not even close). So today I set to "Late collision warning". Too bad for points, I am sacrificing warning assist.

Pretty sure the FCW score is based on "medium" no matter what you have it set to

However, I’ve calculated my score with the three different potential methods mentioned above and it makes a difference of just 0.02 (not 2)

Yeah, for people with scores already 95+, any difference is probably lost due to rounding. For others wondering how the different calculations matter…

Day 1: 6% hard braking from 6 seconds / 100 total braking seconds over 10 mile drive
Day 2: 0% hard braking from 100 total braking seconds (other times excluded by braking on Autopilot) over 90 mile drive

Day 1 score = 83.8 -> "84"
Day 2 score = 100

Overall score…

1. if score weighted by miles: (83.8*10 + 100*90) / 100 = 98.4 -> "98"
2. if factors weighted by miles: hard braking (6%*10 + 0%*90) / 100 = 0.6% for 98.9 score -> "99"
3. if recalculated from aggregate factors: hard braking (6 seconds / 200 total) = 3% for 93.4 -> "93"

I'm pretty sure it's not the 2nd option as the main/overall screen doesn't show mileage-weighted factors (other than FCW, which the denominator is total miles anyway).

One of our vehicles has option 1 calculating 94.8 vs option 3 calculating 94.9. While the other vehicle has option 1 calculating 99.6 vs option 3 calculating 99.8. But if I recall correctly when the overall score rounded up to 100 for the latter vehicle, it seems to match up with option 1 rounding up from 99.5 as if it was option 3, it should have rounded up sooner.

The setting does not matter. The score is based off the "medium" setting whether it is activated or not.

So based on the polls taken on this thread, about 75% of drivers have a score of 98 or better. And more that 80% have a score of 95 or better.

Anyone who gets a score that high is probably a very safe, attentive driver. Elon says he will segregate the rollout by scores of 100, then 99, then 98, etc.

But really, that's pretty arbitrary. Anyone with a high score should be allowed to get the beta. A 100 driver is no better than a 99 driver.

I guess they just need some way to roll it out slowly.

 

[Silicon Desert]

I found it funny that they are scoring your driving so they could drive for you! If they are doing the driving, why do they care if you break hard or turn sharp when you are driving? Unless... maybe they will only let the people who score low to get onto beta. They want the dangerous drivers off the street!

interesting. If FSD is as good as Elon thinks it is, then wouldn't it make more sense to give FSD to the worst drivers in order to have the car drive better than them

 

[alexgr]

I'll be doing a test today on whether only regeneration will cause hard braking on a flat surface. i am going to do a 0-60 run and once i hit 60 I will let off the accelerator completely and let the car come to a complete stop and see if i get a ding for hard braking. If i don't get a ding on the first run, i will try it again and again for awhile to see what happens.

You may also try to let the car decelerate and stop going downhill or uphill.

.. and then, please try several hard stops, AP disengagement, and, of course, a few hard braking events with FCW. We love to move up in the line for Beta.

Watch Kim Paquette’s FSD 10.1 videos posted last weekend on Twitter during low traffic periods. She lives in a town with ancient, narrow roads so FSD is really tested but her videos show how far FSD has to go before it should be routinely used. Musk should be ashamed of himself every time he gives a breathless tout of the latest and greatest FSD beta. Kim’s videos show why wide distribution of FSD beta is probably a bad idea for Tesla. I want it just as you do, but it is far from a finished, safe product and Tesla may walk into a PR nightmare if the product isn’t substantially improved before wide distribution. Hence the goofy safety requirement of a gamed 100 score.

... right, that top 1%. We need occupy FSD party, I guess.

If you haven't done so yet, can you try it please?

 

[EVNow]

How exactly is rolling out by score, high to low, arbitrary ?

Infact it is exactly the opposite of arbitrary.

To be surely safe, stop the car before entering the garage, put it in park, maybe exit the car and re-enter it, then pull it into the garage. The new trip from your driveway to garage will be less than 0.1 mile and will not be counted.

Brilliant! I will look like a crazy person to my neighbours but in the name of FSD this is a good idea.

Have you watched FSD Beta videos?
This is to prepare you for how you’ll look while using FSD Beta.

 

[brianman]

Does anyone know how they are combining/averaging scores between the days?

From Safety Score Beta:

We combine your daily Safety Scores (up to 30 days) into a mileage-weighted average to calculate the aggregated Safety Score, which is displayed on the main ‘Safety Score’ screen of the Tesla app.

 

[brianman]

Like 80% of Americans, I believe that my driving ability and safety is well above average.

lol

At least 30% are wrong.

 

[Usain]

My point is that the score itself is arbitrary when you are talking about 100 versus 99. You aren't measuring a meaningful difference in driving ability.

You're optimizing backwards.

Early gives you a chance to react so that Medium events don't hurt your score. Setting it to Late means you'll be posting next that you got a bad score and the car never alerted you.
