Are there any concerns with using ceramic fiber in the car from the perspective of having it get dislodged and get into the cabin (I assume it's not particularly healthy to breathe in)? Would other non-fiber foam (e.g., PU foam) have the same sound absorbing effect?

Thanks so much for this reply! This is exactly what I was looking for. Going through all of these things certainly takes time, luckily I have the rest of the long weekend to catch up on the videos. It’s helpful to understand how much of this is really about predicting actions and the response. I...

This is interesting. I’m going to look up the Anguelov talk. I suppose the other piece of this is translating the 3D vector space into recognizable and relevant components (cars, pedestrians, obstacles, bumps, trees, etc.). I would imagine that’s *relatively* solved at this point by everyone.

This is definitely helpful - do you have a sense for what key problems Cruise/Waymo are still trying to solve? What are the big blockers - perception? Driving rules? Something else entirely?

Yes! You clearly are - I've seen a lot of your posts and wish there was some sort of wiki with all of them :). What's your take on the Cruise Under the Hood video - anything new there? It all seems fairly sophisticated, but I would imagine Tesla is doing a lot of the same things in terms of...

Has anyone come across a reasonably detailed comparison of the state of the self-driving tech of the major players (and others)? Something that's: Detailed and technical (i.e., goes beyond "Waymo is Geofenced" or vision vs LiDAR). Broken down to the subcomponents - perception, decision making...

A lot of these arguments smack of the "guns don't people, people kill people" argument. Yes that's true, but that doesn't preclude Tesla from implementing technology to increase the likelihood that a driver will pay attention to the road and to reduce the ease with which these safety devices can...

Best time to raise is when you have leverage, which is when things are looking great. When things are going well, you raise to capture the opportunities ahead, not when you need the money to meet cash flow needs. Look at when companies IPO (which is the same thing). And even if it may look...

My friend and I were lamenting Tesla's financial situation/stock price, especially given how great the product is, and the conversation turned to recent strategic mistakes Tesla has made. Would be curious to get people's take on this and strategic choices ahead of it: 1. Not raising $5-10bn in...

All of these statistics are bunk and no one is doing analysis properly. Tesla is mixing highway/city. NHTSA looks like is just making up a bunch of numbers. And this research report is not much better. Airbag events often total a car (and/or cause the owner to sell it). The second owner of these...

Oh nice! This is exactly what I need. What size do you have the large or x-large?

My lab mix is only about 50lbs, but what I like about the TM3 vs. my past car (3 series) is that the rear seat is very low - so she not only has the cushion, but can easily put her feet down on the floor without toppling over. I don't use a hammock though as it blocks the AC vents in the back...

I took my car to the service center today (for an unrelated issue) and they confirmed that the bolts are totally normal - they were necessary for mounting when the car was getting built I believe.

In due time there will be a lot more information about dimensions, what fits, etc., and more components will come out. This is just the price premium you pay for not having to do the research on what will fit on your car.

Went to the service center for a weird squealing issue today and asked about the bolts - they looked and said that they're just mounting points and that it's totally normal.

For most people getting all that stuff is unnecessary, even if you want to drive quickly. Getting stickier tires will get you 90% of the way there. Brake upgrade is irrelevant except for the track - bigger brakes don't make your car stop faster (so long as the stock brakes are powerful enough to...

This is awesome. I'd love measurements on your suspension height from the wheel cap to the top of the wheel fender. I started a thread on this with my data, and would be great to share. Suspension Height - P3D vs. P3D+ vs. RWD Also - my car has similar built weirdness, e.g., screws with no...

Also - this is a fun thread... P3D+ misc info and pics- wheel weight, calipers, suspension I can confirm my M3 has a few screws with no bolts on them also...

If it seems like a lot to measure - just do a couple wheels from the center of the cap to the top of the wheel fender. No need for 8 measurements.

Err... I measured my car just now, two weeks after receiving it. I didn't have a tape measure at the delivery center when I picked it up. And I used the jeep illustration b/c it was the first clear diagram I could pull off google images without having to make my own. That all said - you're...

I received my P3D without performance package at the end of July. When parked next to RWD cars at the delivery center, it was pretty obvious that my car was lowered slightly (when I ordered it, the performance upgrade package did not list lowered suspension as an upgrade). I'd be curious what...

Exactly. "AEB" as defined by the industry and by apparently almost every other manufacturer that implements it means the car comes to a complete stop, whether or not you're in autopilot mode. That's what I'd expect as a user when I hear "automatic emergency braking." So does IIHS, and they are...

There's absolutely no reason to implement it this way unless the computer has uncertainty about whether there is an object in front of you.

I convinced my parents to buy a 530e (they've consistently owned 5-series sedans for decades) as a step toward EVs. It's a great car and with all the incentives I don't understand why anyone would ever buy a 530i. Drivers assistance systems I think are fairly limited on the BMW, but it's super...

To me it seems clear that the 25mph slowdown and the phantom braking are connected. Teslas clearly have a problem with false positives that cause them to brake unnecessarily (I've personally experienced this a few times in my Model 3). If the computer brought them to a full stop every time it...

Guy from the coffee sleeve video here - I can confirm that the P3D I have (18") has a lowered suspension vs. the RWDs in the delivery center parking lot. We didn't really feel like scientifically measuring it, but it was substantial and obvious. You can tell with your hand right away. 10mm seems...
