WEBVTT Kind: captions Language: en 1 00:00:00.000 --> 00:00:02.400 - No one knows why humans get motion sick. 2 00:00:02.410 --> 00:00:03.660 I mean, we know what causes it: 3 00:00:03.660 --> 00:00:05.630 it's the difference between the motion that we see 4 00:00:05.630 --> 00:00:06.950 and the motion that we feel. 5 00:00:06.950 --> 00:00:08.600 But why nausea? 6 00:00:08.600 --> 00:00:11.800 Why not a migraine or a loss of bladder control? 7 00:00:11.800 --> 00:00:12.990 There's a popular theory that says 8 00:00:12.990 --> 00:00:15.190 it's because our brain thinks we've been poisoned. 9 00:00:15.190 --> 00:00:17.440 Some toxins do mess with your balance. 10 00:00:17.440 --> 00:00:19.240 But that is just a theory. 11 00:00:19.240 --> 00:00:23.103 One scientist describes that theory as not just unproven but untestable. 12 00:00:24.820 --> 00:00:26.560 Anyway, I'm with these reprobates, 13 00:00:26.560 --> 00:00:30.331 and we've made a car that brings video game lag into the real world. 14 00:00:32.180 --> 00:00:33.610 - It lands right on the hazards, 15 00:00:33.610 --> 00:00:37.006 so for when we crash... [laughing] 16 00:00:37.006 --> 00:00:39.431 - Oh, there's two. I felt like I just did a magic trick. 17 00:00:39.431 --> 00:00:41.540 - It's upside down!
