- No one knows why humans get motion sick.

it's the difference between the motion that we see

Why not a migraine or a loss of bladder control?

it's because our brain thinks we've been poisoned.

One scientist describes that theory as not just unproven but untestable.

and we've made a car that brings video game lag into the real world.

- Oh, there's two. I felt like I just did a magic trick.

Inside this shrouded driving compartment...

The driver can see the view projected on this monitor,

and that view is coming from this front-facing camera just here.

as it runs through the passenger seat computer,

- Now, we are not running a proper double-blind scientific experiment here.

But, from our rough results, here's what we found.

If the view is only very slightly lagged, the brain just copes with it.

It's weird watching a screen to pilot a car,

- Where's the shifter? Where's the shifter?

If the view is very lagged, by more than a second,

then the brain treats it as two separate tasks,

This is actually, I think, a little nauseating.

I don't know. I actually, like, I don't feel sick.

- You can drive and you feel those reactions,

and you use the old view to plot your course,

It's a bit confusing and a bit nauseating, but no more

than looking at any other screen in a moving vehicle.

Oh, I don't like this! I don't like this at all!

Like, in motion simulators this is what you find.

You can trick the body, as long as it's doing a little bit of movement,

But there's this weird spot between those two,

where the view is just lagged by a fraction of a second,

enough that the brain is trying to reconcile

the movement and the view but failing constantly.

Awesome. I'm gonna go ahead and vomit into that bucket if you don't mind.

- Oh my God! That is the worst thing ever.
