"Using #Apple's CarPlay system slowed drivers' reaction times nearly five times as much as driving with a blood-alcohol level of 0.08 — but CarPlay is legal on U.S. vehicles, even as U.S. regulators spend millions on anti-distracted driving campaigns to politely request drivers not use it."

@urbandata this is quite surprising. I feel like texting would be higher than the CarPlay system would be

@mvan231 @urbandata I think it's mostly because touch on a flat panel requires full visual engagement, unlike physical controls. Still, I wonder where tuning an analog and a digital radio would fall in here. Also, I assume there must be some touch screen interaction to get 35% out of the voice interactions with Siri/Google, even if it's just looking at a map?

(And I wonder what they were using to trigger voice—some cars allow steering wheel voice activation, some don't.)

@heavyboots @urbandata all valid points. It's interesting data nonetheless

@urbandata @trs I can’t find any of this mentioned in the actual study? https://rosap.ntl.bts.gov/view/dot/65623/dot_65623_DS1.pdf is it a different study or what? Interested to see how they measured this effect!

Study: Motorists using Apple CarPlay are more distracted than drunk drivers

Researchers concluded using Apple CarPlay or Android Auto while driving is more distracting than driving drunk or high. Reaction times increase by up to 57%.

@urbandata

Distracted driving is still distracted; but the differences between Android, Apple, handheld phone, and texting are interesting. The degree of severity is also very interesting, too.

Just between the interfaces, I wonder how much design and/or buttons vs. glass matter. But in its totality, I guess the real question should be whether we should have distractions in the first place.

@ms @urbandata And comparison to scanning for a radio station, flipping over and fast forwarding a cassette to the song you want, and digging through the big book of CDs to find the perfect one. About the only time I interact with my touchscreen in the car is before I’m driving and at stoplights.

@urbandata not sure if it's taken into account in the study, but if you're drunk/stoned, it's for the whole trip. One needs to take into account something happening at any point while driving vs specifically at the time the driver is engaged with high distraction activities.

Toddlers, not mentioned in the figure, are both highly distracting and can persist in their distraction for entire trips... In my experience.

Many years ago I helped process data on distracted driving for a naturalistic study (aka they put cameras in people's cars and then just let them drive around) some takeaways from that:

  • By far the biggest correlation was between seconds eyes were off the road & accidents. Didn't really matter much what you were doing.
  • People took their eyes off the road an alarming amount of time, checking their phone, eating, reaching into the back seat, etc.
  • You'd think knowing you had a camera watching you would change your behavior, lol nope didn't seem that way.

    @urbandata What are these percentages based upon? 57% of what? A 57% increase of the 1 sec sober reaction time?

    Why isn't having a conversation with your passenger(s) calculated or interacting with a young child in the rear seat? Those have to be exponentially worse reaction times.

    @urbandata People will drive distracted either way, but software is a neat category you can group accidents under. On that list, where is "daydreaming" or "billboards" or "partner broke up with me yesterday" in that list? It's not there because you can't count those.

    @urbandata @Ekas I have never understood the drive to put tablet screens in cars. Buttons make sense, as you can handle them without looking at them.
    I'm glad I've an older car. It will be difficult to find a simple dashboard in those ev's I guess. 🥴

    @urbandata What does using Carplay or Android Auto mean here? Navigation? Playing music? Texting? Without context, I don't see how to interpret this.
