Even the recommended 2 second following distance is insufficient when the vehicle in front of you comes to an immediate halt and there’s no room to switch lanes

Even the recommended 2 second following distance is insufficient when the vehicle in front of you comes to an immediate halt and there’s no room to switch lanes.

The recommended following distance is "Never get closer than the overall stopping distance." [1], so even if the car in front somehow went from 70mph to 0 instantly, you should be able to stop.

  Expecting people to follow that far is like expecting people to read every TOS.

    Dude, we’re talking about explaining away a Tesla failure here. Pedantic analysis of DMV regulations is absolutely essential. Clearly any dolt practicing defensive driving would anticipate the self driving car cutting him off and hard braking. Stories like this make people think that full self driving is actually a car the drives itself fully. The car is safer than any human and by critically thinking about this we are preventing sales and essentially killing people, since Tesla has fewer deaths per mile travelled.

      > Clearly any dolt practicing defensive driving would anticipate the self driving car cutting him off and hard braking. Not sure if you are being serious. How can you tell whether a car is driving autonomously? Expect it from any Tesla? I haven't consciously ever seen a car driving itself. And I like to think of myself being pretty defensive as a driver. I'm not even sure if the feature is available in Australia.

        Of course I’m not being serious. But if there was a video of a Tesla doing anything, the fandom of Tesla is such that defenders would appear.

If you think following the most basic driving safety rule is 'pedantic', please don't drive. > Clearly any dolt practicing defensive driving would anticipate the self driving car cutting him off and hard braking. The Tesla was 100% at fault, nothing can be done when you get cut off like that. But that's not the case for every single car behind them that failed to stop in time. > Stories like this make people think that full self driving is actually a car the drives itself fully. In my opinion Tesla has been criminally misleading with their avertising. The level of gaslighting they've been able to get away with is unbelievable.

    That doesn't reassign fault. It maybe adds more people to the "at fault" group.

    The difference is that not reading the TOS will not kill you. It's also not just some arbitrary rule, it's a fundamental principle based on the rules of physics.

  That is not possible. I know it is impossible, because I am trying. What will happen when you have that distance is that someone will change lanes to what he perceives as huge space between cars. And they will get very close to you initially.

The recommended distance is not 2 seconds at highway speeds. 2s is a rule of thumb for <35 mph; for 50mph, it's somewhere around 4s. But, in any case, it is your obligation to leave as much space as it takes for you to stop your car before it hits the car in front, taking in consideration the speed of both vehicles before braking and the condition of the road. The rule of thumb is there for you as a baseline; blindly following it does not automatically mean that you're in the right if an accident results.
