Tesla Full Self Driving Thread
No one is saying that other automakers have better self driving tech. But in talking about Tesla self driving, Im not sure I agree it the fact that we can't even mention other brands out of comparison if the topic is relevant. It's just interesting if Tesla relies on map data, which is arguably less accurate that realtime signs. Seems like an easy update
Tesla's FSD will drive anywhere including areas with no map data or connectivity. In China people have done some crazy testing, driving Tesla's on roads that only loosely fit that description the car drives perfectly fine. No other system will even attempt this which makes this claim, "Maybe Tesla relies on map data..." ring hollow. As for other systems why not show them? I'd post some Mercedes self driving vids but I can't find any. Waymo vids are easy to find since there are so many Waymo cars out there.
Here's FSD on a "road" it handles it no problem. Old version of FSD.

Not since I sold my Mercedes. Perhaps Steve can quickly demonstrate this.
But Steve, the Mercedes reading an adjacent "slower" speed limit on the freeway was also my issue. I drive on this freeway with speed limit 65, but then there is an exit or secondary 2 lane ramp that is separated by a barrier with 45mph speed limit, but the car would always read the speed limit on the on/off ramp and slam on the brakes.

Nobody is comparing Mercedes to Tesla FSD, we’re just talking about the apparent strange omission of road sign recognition from the experience of a Tesla owner recently shared when cars without that sort of autonomous driving have that. Do we know for a fact whether Tesla does or not?

The answer is yes. It will quickly move away from trucks by speeding up to get past them
Is there a pile of training miles for NYC? This is the best driving I've ever seen in NY including my own and I got very good at it.
If this doesn't convince you that vision only + neural net training is the way forward then nothing will. It only gets better from here.
Magic sauce might not be v14 + HW4 may require v15 + HW5 to reach generalized autonomy at scale. Either way it's going to happen only a matter of time.

there will ALWAYS be edge cases and apparent ‘mistakes’ made by tesla FSD but they will become less and less. some decisions it makes will be called questionable or debatable, but not necessarily mistakes. so critics will always have ammunition. but that doesn’t mean they have a CLUE why the car did what it did. it’s just way more complicated than more than a handful of people on the planet can comprehend specifically.
comparing it to other brands in the u.s. is a joke. there’s simply no valid comparison. tesla is probably a decade ahead and with coming hardware, unlikely to be caught.
my hyundai has “HDA2” which stands for highway drive assist version 2. that means it can drive with hands off the wheel for long periods on interstates. it does very well at lane centering in all cases but won’t change lanes by itself let alone navigate. it does have the ability to change lanes if you initiate with the turn signal but it’s hesitant and so slow it’s fairly useless. meanwhile, my tesla can navigate from door to door through traffic, side roads, onto highways, roundabouts, parking lots, and everything else, boom!
about ‘vision’ detection, people seem to think teslas can only ‘see’ like human vision, another absurdity. the model Y has EIGHT cameras each of which is better than a human eye. i’ve noticed it detects things so far away they haven’t even appeared on the screen (because it would have to squish it down more). it’s that good.
elon musk has said the next hardware Ai5 will be 40x better than Ai4 (i guess he’s calling it “Ai” now “HW” now).
i’m excited to get v14 software soon with my v4 hardware. reviews from those with early access are amazing.
