Check out what happens when we test reversing beeps
on the general public. Almost nothing. They're so used to hearing them,
they don't even react. And the other thing about beeps,
because they're low frequency, it's really hard to tell
where they're coming from. Let me demonstrate... using four guys with anger issues... and one unwitting test subject. I got this shield for you, right?

Check out what happens
00:00:02.021 --> 00:00:05.087
when we test reversing beeps
on the general public.
00:00:07.632 --> 00:00:09.258
Almost nothing.
00:00:09.967 --> 00:00:13.721
They're so used to hearing them,
they don't even react.
00:00:14.043 --> 00:00:18.184
And the other thing about beeps,
because they're low frequency,
00:00:18.267 --> 00:00:21.103
it's really hard to tell
where they're coming from.
00:00:23.397 --> 00:00:24.523
Let me demonstrate...
00:00:25.274 --> 00:00:27.193
using four guys with anger issues...
00:00:28.653 --> 00:00:30.988
and one unwitting test subject.
00:00:31.739 --> 00:00:33.866
