This sort of complexity is why I like pre smog era cars

Tell me about it, I had a 2007 1 series BMW and its transmission computer became dead. Now, I was quoted 4000USD at the dealership (the car was worth about 5000 at that point). I went to a third party specializing in automatic transmission and they almost could do it by swapping the computer from a crashed car. Turns out it needs an encryption key (who only the dealership has) to get the car to recognize the computer…

However, the actual practice of applying the now-legal practice to something like you described is far above the technical skill of most automotive shops. Some tuners may be able to do it, so it might be worth asking around and doing some digging if this happens to anyone else.

There is a smart fuse composed of an inconel alloy that is pyro-actuated to protect from overcurrent conditions when performing a Ludicrous launch (~1500 amp peak current drawn). It's not software only. Very fancy circuit breaker.

Honestly this sounds like /r/VXJunkies is leaking...

I've been having issues with my transmission's cardinal grammeters going out of sync. I've heard if I get a turbo encabulator [0], it would supply an inverse reactive current into the unilateral phase destractors, which would fix the sync issue, but the price tag is more than I can swallow. I might just have to deal with the side fumbling of the ambifacient lunar waneshaft, even if it means having to regularly replace the spurving bearings.

Question for Tesla owners: Is the recharge time ever a problem? Have you ever felt regret from not being able to just pull up to a gas station, refuel, and be on your way?

Part of me drools with child-like giddiness at the prospect of owning one, but part of me hesitates at the thought of taking roadtrips in one.

This is good. It's Tesla focusing on making better cars. More range is good. Faster charging is good. Those are real things. Yesterday's claims about Tesla operating a million self-driving taxis by 2020 were, well, not taken too seriously. The new stuff is all at the high end, though. The $35,000 Model 3 is still absent from the product line.

I find it bad that they hyped it up for so long and then removed it from online sales a month later, but you can still order it over the phone or in-branch.

Plus despite some rumours of 2+ month delays, they are actively being produced and have already been delivered to some customers (https://www.youtube.com/watch?v=sQgjY2SRrck).

Alternative view: they’re desperate to get more high margin model S and X sales because owners are keeping their existing models too long.

Well, lets entertain this idea for a minute and see where it takes us. First understand that the Ludicrous upgrade is only available on the Performance Model S/X which is $99k/$104k to start. There are two possible upsells here, from TM3 to Model S, or from a more basic grade of S to an upgraded Model S. There are very few people who set out to buy a $35k car and then consider the TCO of the TM3 as comparable and dec…

Your calculation doesn't really make sense. Your calculation assumes that the free Ludicrous update offered to existing owners costs Tesla 10,000 USD, but existing customers can upgrade to Ludicrous for 7,500 USD. How does that work?

My assumption would be that the gross margin of the Ludicrous upgrade is closer to 90% than 50%.

Is it any worse than what other manufacturers deal with? The 2019 Honda Accord shares some parts with the 2018 Honda Accord which shares some parts with the 2017 model... when something breaks in my Honda the first question is "do they still make/use this part or did they change it in newer models?"

Gee, I hope they have some kind of system to track that. Maybe software even?

If it's like any of the bunch of MES systems I've seen or worked on, it's utter garbage bordering on crime against humanity.

"Vehicle Identification Number numbers"?

Just like PIN number, ATM machine, CAC card, and "is that a work PC or personal?" It's a very typical construction, for whatever reason.

At least you use LED as a noun. In Poland, I constantly hear people saying "LED diode". I keep correcting this and "PIN number" indiscriminately.

Not surprised. They can't expect people to replace their car every two years as if it were an iPhone.

Time to introduce in-car purchases. Pay to overtake.

Tesla self-driving uses the innermost lane by default. Pay to not overtake.

basically none. I've read that many electric motors are most efficient at 80%+ load...

The problem is more that you hurt efficiency when accelerating fast . I'd rather a moderately reliable increase in range than improved periodic acceleration. Essentially this is: How much does (say) 25-55mph in 2s vs. 4s cost for overall distance in normal traffic. That said I have better things to spend 60k on than a car. (my last car was $18k, and 42k can be used for a lot of good things that aren't a fancy car. Th…

You modulate your rate of acceleration with your right foot. If you want a car that accelerates from 25-55 over 4 seconds, drive that way...

This "continuous deployment" for cars must be a logistical nightmare. To do repairs for a given vehicle, keeping track of what parts are backward compatible would be challenging. What if it's a compatibility breaking change? Then keeping inventory for older cars would become problematic. Unless they do design with maximum compatibility. Then it gets interesting as upgrades are possible. While B.EV cars maintenance is…

I doubt it's significantly different from an ICE repair point of view. I do a lot of car repairs myself, and have done things for friends in the past. One memorable time I was helping a friend who had a Toyota van for work (can't remember the exact model, this was early 90s). It needed new brake hoses. After some messing about with pattern ones that didn't fit, we went to Toyota and spoke to the parts guy who said there were TWENTY SEVEN different options for the front brake hoses on that van, and even having the VIN was no help - we needed to take the original in for him to identify it correctly, as even the microfiche (yes, we're talking that long ago) wasn't accurate enough to identify it - he ordered (I think) 5 in which looked like a match and sent the other four back.

While this is an extreme example, there are plenty of different options on most cars as the manufacturers will source different parts for different markets, and in some cases totally different subsystems which look identical externally but are totally different functionally (immobiliser and ECU on a Mk 4 golf springs to mind).
