Any time you try to fuse data from different types of sensors, you're adding potential for misbehavior. And from what I can tell, a lot of phantom braking was caused by the RADAR data being garbage. So I wouldn't assume that reducing the number of sensor types represents motion away from the goal. From all indications, the reverse is likely true.
Additionally, Tesla was never going to achieve anything approaching FSD with their existing RADAR. It was moderately useful as a stopgap on the highway, but its resolution is useless for determining the speed of small objects in an urban environment. Coming up with an approach for determining whether small-ish objects are moving towards or away from you visually was always a mandatory step in reaching an appropriate level of safety. Even if their sensor fusion had been perfect, absent adequate vision-based object vector detection, they still would have needed to move to high-definition RADAR or LIDAR to get the job done. And that has been obvious for a long time.
I am curious about the rumors of Tesla adding RADAR back some time this month. If they're adding HD RADAR, then my guess is that this is trying to make FSD usable in rain. (It currently gives up on me even with the wipers on intermittent, which is
way worse than highway FSD, and if V11 brings that level of poor performance to the highway, it is going to be a disaster.) If so, that's probably a reasonable thing to do.
Either way, the existing RADAR was crap, and getting rid of it was no great loss, IMO.
I'm a little bit less confident about their removal of the ultrasonic sensors, but we'll see.
IMO, that's a bit like complaining when they start closing in the roof of a building that there are no plans for getting an inspector to sign off on the electrical permits.....
The non-city-street stack has always been a temporary band aid, and the plan has always been to get some future version of a city streets stack approved. They've just gotten it to the point where it doesn't completely drive like a drunken 15-year-old with a learner's permit very often, so of course there's no plan to try to get approvals yet.
But that doesn't mean that they aren't moving in the right direction. What they have done, over the course of several years, is add functionality moving them towards the features that will eventually be required for certification.
- When I got my Model X in late 2017, Autopilot was a disaster. It didn't just have phantom braking. It ping-ponged all over the darn road unless the road was pretty close to straight.
- Within a year, it had navigate-on-autopilot, but the lane keeping was still just barely passable.
- Within another year or two, it was mostly handling CA-17 in a survivable manner, and (after a free hardware upgrade) was stopping for traffic lights and stop signs, albeit with assistance deciding when to continue.
- Now, it can navigate a lot of exits that it couldn't handle before, and has at least some city street driving, including making turns (sometimes), handling roads without lane lines, dodging pedestrians and bicycles, etc.
Each of those things represents a significant step forwards in the technology and in its capabilities. And the underlying hardware and software tech has also made significant steps forwards in that time.
Tesla cars are more expensive to repair largely because Tesla can't even build enough parts to keep up with manufacturing demand. Tesla cars also have a higher rate of break-ins.
How do you figure? FSD beta started rolling out to MCU1 cars with HW3 back in December. Mine has been running it for eight days (during which it was raining almost continuously, so I've barely been able to test it at all, because FSD beta basically won't turn on in the rain, but it is still running FSD beta firmware with the feature turned on.)
The CEO of almost every company is the largest seller. From those to whom much stock is given, much selling is expected.
Three months maybe. Six months definitely.
But seriously, you're asking the wrong question. The correct question is when FSD will actually have all of the
required features for city street driving. Until every required feature is in place, wondering when they'll be perfect enough to blindly hand over control is an absurd question to ask. And right now, I'm pretty sure they do not. In particular, I don't think FSD even attempts to handle:
There are probably a lot of other missing capabilities as well, particularly when it comes to region-specific traffic rules. If they were willing to geofence it, they could probably get something good enough pretty quickly in certain places where they have giant piles of driver data, but that's very different from doing it in the more general case.
There's probably a secret plan somewhere that lists all of those features and prioritizes them. When that list is empty, then you can start talking about how long it will be before all the features are reliable enough to consider allowing the human to not be in control. As long as it can't even avoid stopping in the middle of a railroad track or violating simple posted traffic signs, it isn't even close enough to that point to
start asking "when". But it is getting closer with each added feature.
