  • Sure, but a little rust because they weren’t used isn’t a problem, comes off when you use them, but is an instant fail. The brakes are not damaged or broken.

    All brakes rust when not used. If you drove around in the rain today, then didn’t drive for a few days, you’ll probably have a little rust on your brakes. You go for a drive and then it’s gone.

    If you take your car in for a pre-inspection report, and they see some rust on the brakes, they will tell you to drive it around a bit using the brakes a lot before taking it in to be inspected.

    it’s not an actual problem, and not indicative of a poor quality vehicle.

    Edit: To be clear - the drivers should be using the brakes more to clear them so it doesn’t build up to excessive amounts which may be a problem at some point, but the test fails them well before it’s an actual problem.

    Edit: Also, where the model 3 failed a lot outside of the brakes was the front suspension. There are legitimate problems with the front suspension on the older Model 3s. Those are legitimate fails and are a quality issue (there’s even a service bulletin for at least one of the problems)


  • Tesla doesn’t do a lot of the body work or glass type of things, but if you need a new computer, heat pump or anything like that, it’s going to be with Tesla, and especially anything around the battery/power train. Most 3rd party battery replacements fail early due to all the modules not being levelled properly or some fancy battery term for it.

    They could (and should) open up a lot of that to 3rd parties, but they keep it in house.


  • German TUV Reliability Report

    Those numbers are very misleading, as it includes rust on the brakes.

    EVs don’t use their brakes as often due to regen, and vehicles with one pedal driving where you can come to a complete stop without using the brakes, use it even less.

    A large portion of these failures are from some rust appearing from lack of using the brakes. Using the brakes more frequently, or intentional aggressive braking would clear the rust, but it’s a fail if it’s there when you take it in.

    That’s not to say there aren’t other problems, but it’s not as bad as the dead last 14.7% makes it look, and it’s not wholly about poor quality as the report implies, as that isn’t a quality problem.

    Tesla has some of the better one pedal driving and more aggressive regen set ups as well, so the brakes are used less.




  • I once made a big fuss about a very critical security vulnerability because they didn’t want to deal with it and there were very serious ramifications to the business depending on how it was dealt with. Like the company was exposed to multi million dollar lawsuits over it, maybe more, possibly worse than lawsuits

    It was the only time I’ve ever been classified as not a team player, and they used that incident as the reason in the report.

    Edit: they did eventually deal with it properly, but not before trying to hide it and lie about it to our customers first.



  • Whats also likely is people see the attack coming due to the large validator queue, and they implement some sort of counter measure before the attack can even happen. Unless they let a 2048 eth validator in as quickly as a 32 eth validator, were talking many many months as there’s a massive influx of validators.

    Imagine buying all that eth, and the community seeing the attack coming in advance, and instead saying, were going to lock out new validators after XYZ date, and force them to exit instead.

    It would cause problems no doubt, but there would be a lot of options before an attack and after if they get that far to address it.

    edit: They could also dramatically reduce the allowed validators per day if it was suspected, making the attack take years to even be possible.


  • So a government is going to spend hundreds of billions of dollars to get enough Ethereum to disrupt it, before accounting for the price going up by purchasing hundreds of billions of dollars of Ethereum, and then they’re going to destroy the hundreds of billions of dollars they invested to take the network down, temporarily. Like sure, it’s possible, but once established, it’s not happening.

    It would be more cost effective to do a supply chain attack and introduce exploits/weaknesses to try and make people doubt using it, attack the infrastructure and steal coins from exchanges and other off chain services or smart contracts with bugs, and pass laws to restrict it.

    edit: Oh and there’s also the queue to activate a valid staker. It will take a lot of time to even begin to be able to do this, instead of hoarding/renting asic hardware and turning it on out of the blue.

    Edit: Sorry I’m also wrong, it’s 66% of staked ETH, it’s not half the market cap. So we’d be talking probably upwards of a hundred billion (not hundreds) by the time we account for price increases from having to buy to even start to initiate the attack.

    Edit: I also wonder if the future change to allow a staker to stake up to 2048 eth instead of 32 could quicken the attack (as it’s 1 validator in the queue instead of 64) or if they’ll delay larger validators longer, maybe based on its eth amount? I’m not up to speed on that. But in theory the queue would be 64 times quicker if they can join as quick.
