First Impressions of Tesla FSD V14.3.4: Improvements and Regressions

Tesla has begun rolling out FSD v14.3.4 to early-access testers, and initial feedback is very positive. The build introduces FSD Streak Celebrations, the long-awaited Actually Smart Summon for Cybertruck, and several new FSD and navigation-related UI features.

Early day-one reactions across Model 3, Model Y, and Cybertruck have been strong. Below is a summary of the most common observations.

Improved City Driving

A major change in v14.3.4 is a reduction in low-speed indecisiveness. Earlier versions—particularly v14.3.3—often showed steering wheel jitter at low speeds. Testers report that this hesitation appears resolved, leading to more confident behavior in urban and other built-up areas.

The improvement is especially noticeable in active construction zones. Where previous builds frequently feathered the brakes when facing construction signs or flashing lights, v14.3.4 handles these complex visuals more decisively, keeping motion smooth.

14.3.4 seems to be way better around flashing lights at construction zones.
I’ve only driven through three construction zones this morning so I can’t say for certain - but so far it feels way more confident without the micro jitters from the brakes.

Mad Max is Mad Again

For drivers who prefer the more assertive Mad Max profile, v14.3.4 restores a sharper, more aggressive character. Testers say Mad Max now feels confident again, moving away from the unusually passive behavior that crept in with recent point releases.

On dense city streets, Mad Max executes lane changes more decisively and threads through heavy traffic similarly to its highway behavior. The assertiveness feels more natural and human-like, producing smoother overall driving than prior iterations.

Definitely could deserve more than a dot release, Mad Max is better around city traffic- will test parking now but first drive was great, 35 min zero interventions. pic.twitter.com/Z0FmwjVFf2

Pulling Over

Tesla has added a dedicated "Pull Over" parking option, replacing the previous "Curbside" choice.

Testers immediately noticed the difference. The former Curbside behavior often stopped at a nearby spot that wasn’t close to the destination’s marked entrance.

The new Pull Over option aims for the actual physical entrance, identifying parking aprons, drop-off loops, or clear roadside spaces near the destination, providing more reliable results than before.

Robotaxi-Ready UI

In addition to neural network updates, the refreshed interface pushes the experience toward a Robotaxi-like flow. Updated destination pop-ups, prominent routing confirmations, and predictive arrival notifications make the system feel more passenger-centric.

Missing Turns

As with many early-access builds, not everything is an improvement. A notable regression reported by testers is FSD missing navigational turns, especially when taking highway exits.

Although this may not block a broader rollout, it degrades the user experience by triggering frequent re-routing when the vehicle fails to exit the highway or make the correct turn.

FSD 14.3.4 is basic autopilot. It’s. Not making turns. Caught it on video. This is my 5th disengagement for this issue. pic.twitter.com/DN8JD6W6OR

Because this behavior is showing up across the fleet in more rural areas, Tesla may issue another point release before expanding the rollout.
