There is zero chance I'd stay awake behind the wheel of a level 2 or 3 vehicle.

You need audiobooks or podcasts. Heck, I love taking a conference call while on my commute (handsfree of course) - 80% of it is in the left lane of an interstate.

  The left lane is only for passing, and if you are passing >80% of the cars on the road, you are a reckless driver.
  - ZoeZoeBee 10y ago
    Incorrect, the left lane is only for passing only in certain states, and mainly on roads with only 2 lanes of traffic in each direction. >The Uniform Vehicle Code states: Upon all roadways any vehicle proceeding at less than the normal speed of traffic at the time and place and under the conditions then existing shall be driven in the right-hand lane then available for traffic ... >All states allow drivers to use the left lane (when there is more than one in the same direction) to pass. Most states restrict use of the left lane by slow-moving traffic that is not passing. The table below describes the law in effect in each state. http://www.mit.edu/~jfc/right.html http://www.mit.edu/~jfc/right.html

    Nope. Not all Interstates are 4+ lanes of traffic. Many states simply require slower traffic to use the right hand lanes. http://www.mit.edu/~jfc/right.html http://www.mit.edu/~jfc/right.html

    > if you are passing >80% of the cars on the road, you are a reckless driver. Or you are driving at the speed limit on a 2x2 highway used as a trucking corridor. (For example: most of I-5.)

      Right. In California trucks have a lower speed limit than cars, which results in what feel like pretty dangerous situations. The right lane is pretty much for trucks going 55. The left lane is a combination of: * Trucks going 60-65 to pass a truck in the right lane * 'Typical' cars who are going 75ish * Fast cars who are going 80-90 So there is a huge disparity of speed in that lane -- and that disparity seems like it must be a huge factor in many highway accidents. It always feels really dangerous. I wonder if it is safer than just having the trucks have the same speed limit as the cars.

      The speed disparity can be a huge issue. Drive over the Donner Pass sometime or any major Western highway with lots of trucks and mountainous spots (i.e. most Western highways at some points) and the different speed combinations can be pretty nerve wracking to navigate.

I'm in the same boat as you here. Level 2 and 3 are unsafe for me as an individual. When I drive, actively focusing on the road and driving keeps me awake. When I'm a passenger, the lack of mental concentration plus the gentle rocking motion of a moving car knocks me out within ten minutes. The current Tesla autopilot is obviously working well for many people, but for myself I have to wait until level 4. Anything more hands on than that is inherently unsafe because of my habits.

  What kind of "CARTCHA" challenges and games might be fun to play, to prove to your car that you were paying attention to the road and traffic, yet not distract you from being ready to take over driving? Computer vision and speech recognition could be useful for proving the driver's awake, as well as driving the car itself. https://en.wikipedia.org/wiki/Car_numberplate_game https://en.wikipedia.org/wiki/Car_numberplate_game

    The challenge of driving the car manually, without any hyped autopilot.
    - NamTaf 10y ago
      This. There's nothing else because any other task requires diverting mental focus away from the act of constantly assessing the changing environment around your car. That by definition leads to slower reaction times.
- josefresco 10y ago
  It's the reverse for my wife. She starts driving and within minutes gets tired. She'll switch to passenger and be wide awake for hours.
mikeash 10y ago
I've done a few thousand miles with Tesla's Autopilot and I find it to be much easier to stay awake with it than without. Constantly making little adjustments is pretty tiring. Paying attention to the the road and other cars is enough to keep my attention. Your experience may, of course, vary.

  I don't know how long your durations on the wheel are - but microsleep[1] is notoriously hard to self-diagnose, even for drivers of non-self-driving cars. 1. https://en.wikipedia.org/wiki/Microsleep https://en.wikipedia.org/wiki/Microsleep
  - mikeash 10y ago
    It goes along with overall fatigue, right? I feel a lot less tired after a lot of Autopilot driving than after a similar amount of non-Autopilot driving. As for durations at the wheel, I did a Virginia to Wisconsin round-trip over the holidays, and have done other trips of similar lengths in the past. Of course, I'm not spending more than about three hours at the wheel at a time, since the car needs to charge and I have various physiological needs.

That's why these level 2 systems are supposed to verify that the driver maintains contact with the wheel. Not that you can't necessarily get around some of those restrictions, but the system is supposed to warn you if it detects you aren't paying attention and eventually it's supposed to pull the vehicle over safely so if you fall asleep it won't be dangerous. In addition, not having to spend as much energy just keeping the car on the road may help to prevent getting tired. Then again, maybe it won't have any impact.

I avoid using even cruise control because I know I am a worse driver when it's engaged. I firmly believe I'd be a danger to myself and others for the first 30 seconds if a level 2 or 3 car had to hand control back to me. Modulating my speed keeps me engaged with driving and I use it as the trigger to cycle through my responsibilities. I check ahead / speed, adjust throttle, check rearview mirror, check left mirror, check right mirror, repeat. When the throttle step is gone I find myself losing siutational focus very quickly. I've always thought it was because it was the only action that involved actual physical engagement, all the rest are just eye movement. I just bought a new car that alerts when it's below 4 degrees C about the possible icy conditions, but it only does so after the car has been running for several minutes. By the time it goes off I'm already driving and I mistake it for an engine warning or other catastrophic failure. Every time. I live in Canada, of course it's icy in the winter. Toddlers could have told you that. This is an absurdly dangerous thing to have the car do, because when the beep goes off all my attention is on processing the alert, not about the pedestrian I'm about to run over. I have the same basic fear about getting control of a level 2 or 3 car. All my focus will be on why the car is handing me control, not on the actual task of driving.
