What prevents a new update to revert this or cause other safety problem? Pushing updates in a rush is not a good sigh for critical software.

I'd like to think they have some kind of automated CI with a huge warehouse full of cars that automatically drives around and tests everything with each Git push.

  And it's a demolition derby where only the cars that survive get to pass on their genes/settings to the next generation on the production line.

  The cars are full of actual chaos monkeys.

  They sort of do, it's the general public.

    And they've only killed a few people so far.

  If they did, they wouldn't need the media to find the problems for them. Without CR reviewing every update, how confident can you be that they won't regress the braking?

  This image delights me. "Jenkins, hit the track!" "Immediately, Sir."

Please cite your evidence that this was done in a "rush." It's not like Tesla makes changes in production. They do it first in staging/test/SDDV/etc... like the rest of us.

  A feature landing a few days after Elon Musk asked for it, how much testing/miles was this actually tested? If you have development experience you know that even trivial changes can cause unexpected issues.

    I've had development experiences involving "all hands on deck" overnight testing of an upgrade if the boss thought it was important. Does that count?
    - simion314 8y ago
      Yes, me too, and adding a new thing in a rush because the boss wants it today it usually involves hacks, ugly workarounds, incomplete functionality. Also putting a fix late in the day increases the chance of making mistakes. Btw, why is braking and software connected, I am just curious how can you affect braking with an update, does this mean that a bug/crash will make the brakes not work at all or work not as good as a regular car.

Also in response to an unfavorable review from a magazine. Is Tesla going to push out fixes after a wave of critical tweets?

  - simion314 8y ago
    They should test them more, also why did they not handle the issue before it caused bad PR, it is like they don't care as much for safety as others.

Most likely because they were not aware of the problem. When CR pointed it out, they investigated and fixed it.

        Do you think they are other safety related issues that they are not aware and they are waiting some big negative PR until they notice(people reported issues in the exact place the Tesla killed the driver but was not enough)

> What prevents a new update to revert this or cause other safety problem? One would hope it's a culture of safety first at Tesla where all software changes are extensively reviewed, heavily tested in the real world and using whatever kind of simulations are possible, deployed in a reasonable manner to a small set of cars and only deployed to the main population of cars after a satisfactory amount of time. > Pushing updates in a rush is not a good sigh for critical software. Yeah, it's pretty scary to know the braking software in your car was tested for less than a week.
