"Slo-Mo" TAC Anti Speed TV Ad

Many people were sceptical that driving 5 km/h slower could make a difference to speed on impact.

With the help of crash expert Dr Ian Johnston, and an airfield, it is shown conclusively that a 5km/h difference when braking makes a 27km/h difference on impact.

@npage009 This is indeed correct. I emailed the Professor in this video to ask and he confirmed it to me.

@jamabar When you decelerate, even at a constant rate, you are traveling less and less each second, so it takes a shorter distance to wipe off the lower parts of the speed than the higher parts.

@jamabar it has to do with the kinetic energy of the 2 cars the one doing 65 km/h will have 15% more energy than the one going 60 km/h

[Andymuwukka]

yea dont get how he could possibly be doin 27km/h less unless he has brembo brakes and the other guy has no brake pads or somethin!

@npage009 No, US NHTSA crash tests show that a 56 kph frontal crash in a car like the one shown could be survived with minor to moderate injuries. 32 kph has 32.7% of the impact energy as 56. I think the stunt driver, in a 32 kph impact, would only be shaken up.

@dontbecutk exactly, its just what would happen, because generally they would see the truck before that stage anyway. there is also no certainty that the cars would be that far away in a crash, might be wet, the cars could also swerve to avoid the track, and so on and so on... its just showing the difference 5km/hr makes... like if the truck was another couple of metres away, the second car would have also only barely hit the truck. wish more people could see the video for what it is like u did

[bobba84]

And a GTR doing 80 wouldn't hit it at all...

[jamabar]

i dont get how one hits at 5 k's 5 isnt half of 60, 30?

@Porsche911GT3RSCUP Speeding is for Closed courses and tracks, not the public/open road, where you endanger everyone's lives, not just yours.

[dontbecutk]

@Porsche911GT3RSCUP Yup killing your self is fun? and the truck is stopping because thats how the AD is but yeah your right im sure the truck would of kept going
