  • I am in the National Advanced Driving Simulator at the University of Iowa.

  • It's used to test drivers' reactions in a controlled, repeatable environment

  • and also to test things that would be unsafe in the real world.

  • - Tom's currently in the simulator, undergoing a study

  • to look at driver response to unintended acceleration.

  • The vehicle is going to accelerate quickly

  • without any input from Tom, as if it were malfunctioning.

  • Tom's going to have to identify that this event is going on

  • and press the brake very quickly to bring the car under control.

  • GPS: Turn left at the next intersection.

  • Whoa...

  • Whoa, whoa, whoa, whoa, whoa.

  • That was terrifying!

  • But there's a question I want to answer here.

  • Recently, I did a video while driving.

  • And it was on a dead straight road with very little traffic,

  • and I always felt in control of the vehicle. But was I?

  • Is it actually dangerous to talk into a camera while driving?

  • So, I'm going to spend 15 minutes in this simulator, distracted,

  • trying to give this monologue to that camera.

  • And I'm also going to spend 15 minutes in here, not distracted

  • just driving, and putting my full attention on the road,

  • and the team here are going to analyse my results

  • and tell me how I've done.

  • And given I was just doing 35 in a 25, probably not that great.

  • - The National Advanced Driving Simulator was built to recreate

  • the most realistic driving experience possible anywhere.

  • It has a real vehicle cab in it.

  • We can swap different vehicle cabs, in and out.

  • The motion base can travel 64 feet in the X and Y directions

  • and these are basically steel belts that are connected to

  • large drives on either end and then,

  • the hexapod portion of the simulator is hydraulic,

  • that allows us to experience roll, pitch and yaw.

  • We also have a turntable that can turn 330 degrees in either direction.

  • Overall, it has 13 independent degrees of freedom.

  • We have absolute control of what time of day it is.

  • We have control over the weather and traffic.

  • - And yes, the graphics might not be up to modern video game standards,

  • but after a few minutes in here, with all the motion,

  • your brain just accepts that you're driving.

  • - Very broadly, we are interested in studying the relation

  • between the driver and the vehicle to improve safety,

  • so that encompasses things like driver impairment, driver drowsiness,

  • distraction or intoxication. So we bring drivers in,

  • actually give them a large dose of alcohol,

  • get them in the simulator and we can see how they perform.

  • We've also compared that to things like cannabis,

  • so some of the first studies with cannabis and driving

  • have been done in the simulator here as well.

  • As Tom is driving in the simulator, talking to the video camera,

  • I would expect to see him missing certain information in the driving scene.

  • Generally, we find that interactions that take the

  • driver's eyes off the road tend to be the worst but,

  • even in situations where the driver's looking straight ahead,

  • if their attention is pulled to another task, like talking to a video camera,

  • that can also increase distraction and cause the driver to miss certain things.

  • If the driver crashes, they essentially move through

  • the vehicle or the pedestrian that they collided with,

  • so, we don't simulate the dynamics of the crash,

  • but we are recording that they crashed.

  • We know the velocity of that crash.

  • We know how severe that crash would have been.

  • - So, how did I do?

  • - About as well as we would have predicted.

  • Let me pull up an example, here.

  • A vehicle is going to drive through an intersection.

  • You actually have the red stop sign.

  • - Yeah, I didn't see the stop sign, did I?

  • - Completely missed it.

  • - Whoa, just did not see that.

  • The thing is, I'm actually looking at the road, there.

  • I'm actually... but I'm not thinking about the road,

  • because I'm too busy thinking about what my next line is.

  • - Exactly, we would call this inattentional blindness.

  • This is when your attention is off the road,

  • even though your eyes are there.

  • You're missing information that's out in the environment.

  • - Wow.

  • - So, we saw quite a bit of swerving at the beginning of your drive,

  • you had some trouble controlling your speed.

  • You were going about 35 through a 25 school zone.

  • Textbook case of distracted driving.

  • - So, I basically, shouldn't film while driving.

  • - Generally speaking, yes.

  • - Thank you so much. - Thank you.

  • - Thank you so much to everyone at the

  • National Advanced Driving Simulator at the University of Iowa.

  • Pull down the description or click the link on screen for more about them.

  • All the pedestrians here are just suicidal. All of them.

  • This is not a stop sign. I can just take this.

  • Whoa, no I can't. You're coming in from the right.

  • Probably shouldn't check my phone while I'm driving.
