V11.4.2 is the second model of FSD Beta after the supposedly revolutionary enhancements going from V10 to V11.
There have been intense discussions on the net currently about big advances in synthetic intelligence (AI). Apparently, packages like ChatGPT have reached a stage the place they will reply conversational questions and write essays and poems, make medical diagnoses, write authorized briefs, and create photos and films that do a reputable imitation of what a reliable skilled particular person, digicam, or video digicam can do. This progress has come from utilizing big new supercomputers with massively parallel NVIDIA model graphic processors repurposed to coach on huge complete datasets.

What are the implications of those advances in synthetic intelligence for automated driving packages? Tesla is utilizing one of many 10 largest computer systems on the planet to course of knowledge from my automotive and as much as 400,000 different vehicles utilizing FSD Beta to “prepare” future variations of the software program. The Tesla strategy makes use of cameras that substitute for human eyes and a Tesla customized “supercomputer” utilizing neural nets that attempt to imitate the advert hoc brainy selections {that a} human makes. Tesla just isn’t utilizing the strategy that another firms have used of fully mapping the driving setting so that every one the selections the automotive makes are specified forward of time.
What’s my tackle how that is figuring out to date?
We lately have been capable of obtain the second V11 model of Tesla’s Full Self Driving Beta (V11.4.2). We’re spending the summer season in rural Northern Wisconsin, so my means to guage it in heavy site visitors and complicated conditions is restricted. Nonetheless, there are nonetheless issues that we are able to consider right here.
Within the low-traffic state of affairs right here, I can typically put an deal with into the navigation and have it drive me the entire route with out intervention. A giant benefit to FSD Beta over common Autosteer right here in Northern Wisconsin is that the automotive will drive mechanically and precisely on roads with no strains (no yellow strains within the heart and no white strains on the perimeters of the street). It should additionally precisely navigate sharper turns than Autosteer.
One of many points about earlier variations of FSD Beta was too-timid (sluggish) conduct at cease indicators. I’ve been making quantitative observations of V11.4.2 conduct at cease indicators. V11.4.2 now at all times stops my automotive on the right place at cease indicators. This wasn’t at all times true earlier than. The following query is how timid it’s at cease indicators. When leaving my home right here, I’ve two cease indicators the place a smaller street tees into a much bigger street and later tees right into a state freeway. I’ve been timing the interval from full cease to brisk acceleration. If the visibility of the larger street is sweet, I’m seeing a pause of ~3 seconds till brisk acceleration. Sadly, I didn’t measure this pause on the earlier V11 model, so I don’t know if that’s an enchancment. 3 seconds is fast sufficient that I don’t suppose a automotive behind me can be considerably inconvenienced. If the visibility of the larger street from the cease signal just isn’t good, the automotive creeps ahead for a greater view and it takes a complete of ~5 seconds to brisk acceleration. If there’s a automotive behind me or a automotive within the distance approaching on the freeway, I’ll add slightly accelerator encouragement.
Phantom braking
For all 11 variations of FSD Beta that I’ve used, phantom braking has been a difficulty. Nonetheless, I discover it to be an annoyance slightly than a present stopper. Phantom regenerative deceleration is perhaps a greater time period typically. When utilizing FSD Beta, my proper foot is at all times resting evenly on the accelerator. If I’ve a phantom braking occasion and there’s a automotive behind me, I apply some strain to the accelerator to maintain from slowing down considerably. With no automotive behind me, I let the automotive decelerate and pace again up. I attempt to observe the “non-intervened” conduct of FSD Beta at any time when attainable.
I’ve noticed new conduct with the final two variations of FSD Beta. I name it phantom swerving! I see this fairly incessantly on the two-lane roads the place I often drive right here in Northern Wisconsin. The automotive acts like there’s a particular person or object in the midst of my lane. It swerves abruptly into the opposing site visitors lane and again. As soon as it even swerved onto the shoulder of the street. I intervened as a result of I assumed it would drive off the street. The issue: There was nothing that I might see that justified this swerving.
For six months, my spouse and I used 10 variations of FSD Beta V10. We lately received the so known as “revolutionary” improve from V10 to V11. This improve was supposed to include massive enhancements that Tesla has been engaged on for a very long time. We received our improve to V11.3.6 slightly over a month in the past. In a earlier article, I reported on my first impressions. This text is my report on what I’ve noticed with the most recent model, V11.4.2.
FSD evaluation abstract
Sure, there have been vital enhancements. For instance, when working appropriately, FSD Beta V11 strikes you over and will get you into the right flip lane earlier. The lane modifications are additionally a lot smoother. You additionally get a wider blue pathway heart line that allows you to know that FSD Beta is energetic (as proven within the image on the high of this text). You continue to have the choice of FSD-only on limited-access highways, which provides you a narrower blue heart line, or Autosteer-only, which provides you two very slender blue strains on all sides of the lane.
Nonetheless, nonetheless too incessantly, FSD Beta places you within the unsuitable lane. The worst is when it places you right into a flip lane when the navigation requires going straight. This, to me, is the most important failure of the present system. Word: Right here in Northern Wisconsin, I don’t get an opportunity to watch this typically. Nonetheless, the city of Rhinelander (inhabitants 8,308) is 25 miles to our south. In the present day, whereas nonetheless in Rhinelander as we returned to Three Lakes, FSD Beta wrenched my steering wheel and put me right into a flip lane that was inconsistent with the navigation route. So, it’s clear that FSD Beta V11.4.2 has not solved this downside.
Why haven’t these issues been mounted? Tesla has big groups of software program specialists engaged on their whole AI strategy. But, I’ve seen no enchancment in phantom braking and unhealthy lane selections within the 11 variations of the software program I’ve used. My take: The AI strategy Tesla is utilizing doesn’t deal with these issues.
I’d love to listen to about your experiences with FSD Beta within the feedback part. Have any of you noticed phantom swerving?
