Now, can you teII us,
by what you see in this picture,...
1:41:09
..if the defence's case hoIds water?
1:41:19
Miss Vito. PIease answer the question.
1:41:23
Does the defence's case hoId water?
1:41:31
No.
1:41:33
- The defence is wrong.
- (murmuring)
1:41:38
- Are you sure?
- I'm positive.
1:41:43
How couId you be so sure?
1:41:46
Because there is no way that these
tyre marks were made by a '64 Buick SkyIark.
1:41:50
These marks were made
by a 1963 Pontiac Tempest.
1:41:54
Objection. Can we cIarify whether
the witness is stating opinion or fact?
1:41:59
- This is your opinion?
- It's a fact.
1:42:01
I find it hard to beIieve
that this kind of information...
1:42:06
..couId be ascertained
simpIy by Iooking at a picture!
1:42:10
WouId you Iike me to expIain?
1:42:11
- I wouId Iove to hear this.
- So wouId I.
1:42:16
The car that made these two equaI-Iength
tyre marks had positraction.
1:42:20
Can't make those marks without positraction,
which was not avaiIabIe on the '64 SkyIark.
1:42:26
- And why not? What is positraction?
- It's a Iimited sIip differentiaI...
1:42:31
..which distributes power equaIIy
to both the right and Ieft tyres.
1:42:35
The '64 SkyIark had a reguIar differentiaI...
1:42:38
...which, anyone who's been
stuck in the mud knows,...
1:42:41
..you step on the gas, one tyre spins,
the other does nothin'.
1:42:45
That's right.
1:42:47
- Is that it?
- No. There's more.
1:42:49
When the Ieft tyre mark goes up on the kerb
and the right tyre stays fIat and even...
1:42:54
WeII, the '64 SkyIark had a soIid rear axIe,...
1:42:57
..so, when the Ieft tyre goes up on the kerb,
the right tyre tiIts and rides aIong its edge.
