He's parking the Jag.

[the Wheelman is driving the getaway car after the robbery and hears on the police radio that the police are getting very close] The Wheelman:
I used to live round here. Hold tight. [he swerves onto a farm track, through some greenhouses and heads towards a fence] Guv'nor:
[shouts]
That's a bloody fence! Christ! Where are we going? You stupid... Where are we going now? The Wheelman:
[calmly]
We can cut through round here, back onto the estate. Donkey:
[shouts]
There's no road. Where is it? There's no road! [the Wheelman sees two garages with a narrow gap between them] The Wheelman:
Shit! These weren't here last year. Donkey:
[ironically]
No? Well they're here now! Guv'nor:
[shouts]
Where are you going, Richie? The Wheelman:
Trying to get us out of here. Guv'nor:
[shouts]
It won't work! [the Wheelman tries to get through the gap, but the car jams, so he reverses and tries again, repeatedly] The Peterman:
Can we get out! The Wheelman:
That's what I'm trying to do. The Peterman:
No, get out and walk. Donkey:
[explains, as if to an idiot]
Look, you don't understand the basic laws of physics. The hole is too small. [after many attempts, the Wheelman manages to get the car through the gap] Guv'nor:
Have you *any* idea where you're going? [after narrowly escaping being crushed by an oncoming coach as they overtake a lorry, they arrive at some waste ground] The Wheelman:
[apologetically]
Sorry about the last bit, Guv. Bit untoward. Guv'nor:
Don't worry, Richie. Anyone else would still be modifying greenhouses. Be lucky, son. [the Wheelman walks away and the rest of the gang get into a van] Guv'nor:
Come on! Let's get this bloody show on the road! The Peterman:
What about the driver? Guv'nor:
He's parking the Jag. [shot of the Wheelman in a JCB, pushing the car down a bank into a lake to hide it]
