Here's our new car It gets great gas mileage, it has leather seats, buy our car.

And also it turned out these bench seats are the very best way to install car seats.

So they just have these bench seats, and they strap the car seat and the seatbelt onto it.

This is a car seat that was installed by someone who has installed 1,000 car seats, who knew exactly how to do it.

A seat works in a two dimensional world, where gravity blasts down on that seat, OK?

That's my ejection seat.

I would like you to approve it for selling, then they would say, This is a fantastic new car seat, it works great.

Having a flat back makes it much easier to install them.

The car seat's moving all over the place.

And this crash would have been about a 450.

In a fighter, you have an ejection seat.

And so this is a test that's very much rigged in favor of the car seat, OK? So, that kid in this crash fared very well.

And I think this gives you a good idea of why parents think car seats are so great. Look at the kid in the car seat.

And these, to me, are the analogy for the car seats.

So, in some sense, what this is suggesting is that it's not just that people are setting up their car seats wrong, which is putting children at risk. It's just that, fundamentally, the car seats aren't doing much.

If you put a child in a car seat, 18.2 percent of the children die.

Well, that's typical of a lot of us working in chairs.

I'd designed a lot of chairs, over the years for tractors and trucks and submarines all kinds of things.

Mary placed her baby in a car seat for the flight.

So here this is the car seat. Now watch two things watch how the head goes forward, and basically hits the knees and this is in the car seat and watch how the car seat flies around, in the rebound, up in the air.

When asked, they said, It's kind of like a giant toilet that doesn't flush.

Bear in mind there are two things about this.

It doesn't turn out to be the case when you look at seatbelts versus car seats.

So if somebody can reach under the chair that s next to them, you ll find something taped underneath it.

And so if we look at recent crashes the whole data set is almost 30 years' worth of data you won't see it in the recent crashes. The new car seats are far, far better.

And the other thing you might argue is, Well, car seats have got a lot better over time.

It's a comment on the way in which we deal with public seating in the city of New York.

But what's interesting is the government telling us to use them is not actually based on very much.

I said we can shorten the column, we can spread it out to cover the couch.

Here you see the chairs being spun around to go from proscenium or end stage to thrust configuration.

Your seat, your sleep and your play on a big geodesic island made of leather.

But indeed, in recent crashes the lap and shoulder seatbelts, actually, are doing even better than the car seats.

So this car seat was actually an above average car seat from Consumer Reports, and did quite well.

And this seatbelt would have passed with flying colors into being approved as a car seat.

Is Microsoft a great big anthill?

We can't risk alienating them by testing seatbelts relative to car seats.

And this is, again, one of those assumptions the way car seats are an assumption that we've inherited in governments, and doors.

Even if they're right, it's not so clear that they're so cost effective.

So here's the crash. So these are timed at the same time, so you can see that it takes much longer with the car seat at rebound, it takes a lot longer but there's just a lot less movement for child who's in the seatbelt.

There is also a small newly constructed building for medical purposes.

So here we are using 20 million barrels a day producing eight, importing 12, and from the 12, five comes from OPEC.

But when you look at other types of crashes, like rear impact crashes, indeed, the car seats don't perform as well.

The balconies come down, you see that the orchestra begins to have a rake that's frontal towards the end stage, and the seats come in.
