Tesla uses the Predicted Collision Formula (PCF) to calculate all of the above factors. This formula predicts how many car accidents may happen per 1 million miles driven.
This new version 1.2 adds features like a visualization of your trip (without location data to protect privacy), Late Night Driving and an increased grace period from three to five seconds.
Here is a list of the changes to Safety Score:
Provided a visualization of your trip, as a timeline, to show when specific events that impacted your Safety Score occurred. To protect your privacy, no location data is provided.
Added Late Night Driving as a new Safety Factor. More time spent driving at night will lead to a lower Safety Score.
Increased grace period after Autopilot disengages from 3 seconds to 5 seconds.
Updated hard braking and aggressive turning Safety Factors to count the number of events instead of the duration of events.
Updated Forward Collision Warning rate Safety Factor to calculate the rate of warnings per 1,000 miles driven while not using Autopilot.
Updated Safety Score to use the miles-weighted average of the last 30 day’s Safety Scores, ignoring any miles driven on Autopilot.
One of the biggest upgrades to version 1.2 is the addition of Late Night Driving. Tesla notes in their blog post that, “Late Night Driving is defined as the number of seconds you spend driving at night (10pm - 4am) divided by the number of seconds you spend driving total in the day.” Although Late Night Driving is capped at 29.3% of your total score.
The reason Tesla has added this as a safety factor is that driving at night can be more dangerous due to reduced visibility, tiredness, and distractions.
According to the National Safety Council, most fatal accidents occur between 4pm and 11:59pm, with Friday, Saturday, and Sunday being the most frequent accident days.
Tesla’s new trip visualization feature in version 1.2 is also a welcomed improvement. Previously, drivers were not given detailed feedback about their drives. Instead, they were just given an adjusted score. Trip visualization will show drivers when their trip started, when Autopilot was engaged/disengaged, the time of the infraction (if any), and when the trip ended.
These insights will hopefully allow drivers to reflect on each drive and correct any aggressive driving in order to receive Full Self-Driving beta.
Although Tesla has launched Safety Score v1.2, some drivers will remain enrolled in the original version. You can see which version you're enrolled in by scrolling to the bottom of the Safety Score screen.
Tesla is getting ready to introduce WiFi garage door support to their vehicles through MyQ.
Since our article yesterday additional details have emerged about how MyQ will operate, which vehicles will be supported and whether there will be a cost to use the service. This information is based on a page that appeared briefly on MyQ's website but has since been removed.
MyQ's website stated that support for their garage door openers would be coming to the Model 3 and Model Y. While this makes a lot of sense because those vehicles don't include a HomeLink module, we'd be surprised if Tesla didn't also add support for the Model S and Model X.
Let's get cost out of the way. Although MyQ does not charge a fee today to remotely open and close their garage doors, they do plan on charging a fee to use their devices in vehicles. This could be looked at similarly to how some services are free to use on a PC but require a subscription to use on your mobile phone.
The price posted on MyQ's website was a five-year plan for $179, which is still cheaper than Tesla's $350 installation cost for HomeLink.
Unfortunately, this removes a big benefit we thought MyQ would have over buying a HomeLink module for the Model 3 or Model Y. For Model S and Model X owners who already have HomeLink included in their vehicles, it may not make as much sense.
However, MyQ does provide some advantages over HomeLink.
The good news is that MyQ integration will be very similar to HomeLink, and better in some ways. What appears to be a rendering of the feature working in a Tesla was also posted to their website which shows off a screen very similar to HomeLink.
On the MyQ settings screen, you'll have a list of supported devices on the left side, such as garage doors, gates and possibly lights, but we haven't see any evidence of the latter yet.
On the right side, you'll see options pertaining to the device selected, such as its current state, whether the garage door should auto-open or close and the distance when the device should be triggered.
You'll also be able to have the vehicle fold in its mirrors when reaching the target location.
If you've used HomeLink, this should all look very familiar since it's almost exactly the same. However, there are a couple of differences that give the advantage to MyQ.
The first is that MyQ is a smarter system and it knows the state of your garage door. So if you're arriving home and the garage door is already open, it won't try to close it on you.
The other advantage is distance. Since MyQ works over the internet you'll be able to trigger the garage door or gate from further down the driveway, giving the door plenty of time to fully open before you arrive.
MyQ supports an array of devices, but it waits to be seen whether there will be support for these additional devices such as lights and door locks.
Tesla requested more time for details to be kept confidential, and in doing so, everyone now knows something is up. A document dated November 18, 2022, appeared on Twitter on December 6. It’s from Tesla Inc. and addressed to the Federal Communications Commission. In the brief letter, Certification Engineer Cindy Li requests a 60-day extension of a previous agreement to keep a device secret. This mysterious letter set the Tesla sphere on fire with speculation to find out what is the secret device.
All we know from the letter is that model number 1541584 includes a user manual, internal photos, external photos, and test setup photos. Whatever this device is, it was going to be made public by the FCC on December 7, 2022. Tesla asked for an extension because the device will not be ready until mid-January 2023. The company wants to “avoid any unnecessary disclosure and competitive harm before our product launch…”
The poster of the letter, Twitter user @Taka87 reached out to well-known Tesla hacker @greentheonly, for some insight. The response: … something potentially major planned for mid-January which is just a bit over a month away... Like something that coincides with a sensor suite change.
That opens the door for the return of radar, which was removed last year and/or ultrasonic sensors, which Tesla just scrapped in October when it made the call to go completely with Tesla Vision. At that time, Tesla said in a statement: With today's software, this approach gives Autopilot high-definition spatial positioning, longer range visibility and the ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time.
There has also been a lot of speculation about HW4, where a high-resolution radar is believed to be part of the full self-driving sensor suite. HW4 goes as far back as the 2021 A.I. Day when Elon Musk said a new FSD computer would come out with the Cybertruck. This upgrade is now reportedly being developed by the Taiwan Semiconductor Manufacturing Company Limited (TSMC). It is expected to be much more powerful than the current hardware by as much as four times.
Elon has also previously commented on HD radar, saying "A very high-resolution radar would be better than pure vision, but such a radar does not exist. I mean vision with high-res radar would be better than pure vision."
An unidentified part, closely resembling a new radar was found on Tesla's Parts Catalog back in September by @GreenTheOnly. This mysterious item was marked but suspiciously not given a name, a part number or a description. However, given Green's experience with the inner workings of these vehicles, Green believes it is a new Tesla radar. In a follow-up tweet, he doubled down on his stance, saying the part matches the high-resolution radar Tesla registered with the U.S. Federal Communications Commission in June.
