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 recently showed off Giga Small Haus, an interesting new display project hosted at Giga Berlin. The small new house is located just outside the main entrance of Tesla’s Giga Berlin factory, with a Quicksilver Model Y parked inside.
Giga Small Haus is powered only by solar and Powerwall 3 - disconnected from the local grid and from Giga Berlin itself. It serves as a live demonstration of Tesla Solar and Tesla’s Powerwall battery backup.
Giga Small Haus
The centerpiece of the display is a Model Y in Quicksilver - a beautiful pick for a beautifully lit house. However, that’s not the real focus here - it's the Powerwall and Gateway on the wall.
The Powerwall is the focus of Giga Small Haus, and there’s a display with some additional information on the wall. Part of the display also includes a screen that displays the current output of the Powerwall itself versus the consumption of Giga Small Haus, as well as the input from solar.

Not a Tesla App
The text on the exhibit is divided into several sections. Here’s a translated and edited version of what we can see from Tesla’s images. Some additional text is obscured. If someone visits Giga Small Haus, let us know.
Powerwall
Powerwall is a home battery system that stores energy from solar panels, the electrical grid, or during off-peak hours and powers your home during the day or during a power outage.
With Powerwall, you can use self-generated solar energy during the day and night, thus avoiding high electricity costs. You can also store excess energy produced during sunny periods for use during times of low production or power outages.
Key Features
Energy Storage: Powerwall stores excess energy from solar panels or the grid for later use or during power outages.
Backup Power: In the event of a power outage, Powerwall automatically switches to battery power to ensure continuous power supply.
Integration: Powerwall can be seamlessly integrated with existing solar systems and other power sources.
Scalability: Multiple Powerwalls can be installed to meet higher energy storage needs.
Smart Energy Management: Powerwall works with Tesla's software to optimize energy consumption and reduce costs.
How Powerwall Works
Storage: During the day, when solar panels produce more energy than needed, the excess is stored in Powerwall.
Usage: At night or during times of low solar production, the stored energy is used to power the home, reducing reliance on the grid.
Backup: During a power outage, Powerwall automatically provides power to critical circuits, ensuring continuous operation of essential appliances.
Benefits
Cost Savings: By storing and using solar energy, you can reduce your electricity bills.
Reliability: Provides backup power during outages, ensuring your home remains powered.
Sustainability: Promotes the use of renewable energy by storing excess solar production for later use.
Overall, Giga Small Haus is an interesting real-life demo of what Powerwall and Solar can accomplish. It would be neat if Tesla built more of these displays - perhaps near major Delivery and Service Centers and at Giga Texas, Fremont, Giga Shanghai, and other facilities. Many Tesla owners have yet to learn about and experience some of Tesla’s Energy products.
Tesla has added the Acceleration Boost option to the Tesla store for owners of the 2024 Model 3 Long Range - specifically owners in Australia and China. Acceleration Boost is an upgrade that provides a significant performance boost, drastically narrowing the performance gap between the Long Range and Performance versions of the same model.
This upgrade will likely become available in Europe, Canada, and the United States in the next few days as Tesla updates its shops globally.
Acceleration Boost
This new Acceleration Boost is retailing for $3,000 AUD, or approximately $2,000 USD. That’s the same price for current owners of older Model 3 or Model Y Long Range vehicles, which all have the option to purchase Acceleration Boost through the shop.
The boost provides improved 0-100km/h (0-60mph) performance, bumping the 2024 Model 3 LR from 4.4s to 3.8s. The 2024 Performance version comes in at a blazing fast 2.9 seconds, so while it isn’t equivalent to just buying a performance variant in the first place, it is still a noticeable and significant upgrade.
Performance variants also come with a different front fascia vent for cooling, performance drive units, sport seats, adaptive suspension, 20-inch wheels, and Track Mode V3. That’s a significant number of additional features in the $10,000 USD price difference between the Long Range and Performance versions.
Should You Buy It?
If you’ve purchased a Long Range model and are itching to go just that little bit faster at every red light, this is the upgrade for you. It previously came with the cost of slightly reducing vehicle range, but the Tesla store doesn’t make a note of reduced range this time around. The 2023 Model 3 and Model Y Long Range models had an efficiency loss of about 5% due to the additional always-available acceleration and cooling.
You could drive in Chill mode to mostly negate that efficiency loss, but what’s the fun in driving in Chill when you just got Acceleration Boost? Anyhow, the shop listing for the 2024 variant doesn’t include this detail, so it's possible Tesla may have worked some more engineering magic.
Overall, if you’ve got the $3,000 AUD burning a hole in your pocket, some Tesla referral credits sitting around, or just want to go faster, it's definitely an upgrade many users find valuable.
