Exploring Full Self-Driving Technology: A Comparative Test

On a chilly January day in the northwest suburbs of Chicago, John and his friend Corey put Tesla's Full Self-Driving (FSD) technology to the test. With John's Model 3 lagging behind Corey's Model Y, equipped with the latest Hardware 4, the two aimed to explore how the two versions of FSD reacted in various driving situations, especially regarding tailgating.

The Setup: Models and Conditions

Part 2/7:

As the temperatures hovered around 5°F (-5°C), John explained that while Corey's Model Y was enjoying the new FSD update, his Model 3 was still awaiting the upgrade. Despite the cold, both drivers were eager to compare the capabilities and responses of their respective vehicles, particularly focusing on how the FSD technology managed interactions with tailgating.

Initial Testing: Residential Streets

Starting their test drive on neighborhood roads, John activated FSD and asked Corey to tailgate his Model 3. To their surprise, they observed an immediate response; John's car accelerated when Corey got close. However, after further experimenting, John aimed to ensure that the increased speed was indeed a reaction to Corey's vehicle.

Part 3/7:

This led them to navigate through residential zones, noting the speed limits and how the FSD system handled closer proximity. In these conditions, John’s Model 3 demonstrated a marked increase in speed and responsiveness compared to the seemingly more docile version running on his Model Y.

Highway Dynamics: Switching Tracks

Once they felt confident about the residential street responses, they turned their attention to highway driving. John switched roles and tailgated Corey’s Model Y with FSD engaged. He noted that despite the increased speed and the potential risk involved with being closer, Corey's vehicle did not speed up in the way John's Model 3 had on city streets.

Part 4/7:

They noted that while John's Model 3 was permitted to vary its speed based on proximity, Corey's Model Y remained steadfast, maintaining its own pace regardless of how close John got. The difference in behavior was particularly striking when they considered the contrasting dynamics between residential and highway driving.

Observing Responses: FSD Version Comparisons

Part 5/7:

The duo concluded that the differences in FSD behavior were highly pronounced between the two versions. While John's Model 3 displayed an ability to accelerate in residential areas when tailgated, Corey's Model Y with the most recent updates showed resistance to such behavior. The lack of urgency on the highway revealed one key point: the FSD system operated distinctly based on the type of road and the set parameters, contrasting a more reactive city stack with a more set highway stack.

Implications and Safety Considerations

Part 6/7:

As they wrapped up their comparisons, John and Corey pondered the implications of tailgating responses within FSD systems. Observing that, although adaptive capabilities could enhance road dynamics, there were reservations about the need for cars to respond aggressively to tailgaters in lower-speed environments like neighborhoods. Both drivers felt that it was unnecessary for vehicles to increase speeds merely due to impatient drivers behind them.

Part 7/7:

In conclusion, their shared experiences shed light on the evolving nature of Tesla’s Full Self-Driving technology, highlighting significant differences between versions and stressing the importance of maintaining safe driving practices, regardless of the capabilities of automated systems. As always, the advancement of technology brings both opportunities and challenges, which drivers must navigate thoughtfully.
