Jump It (Pt 2)

So with the Pirates of the Carribean soundtrack playing in the background (another iTunes purchase) I shall try and finish up my little random story.

The driver dropped the vehicle into neutral and spun it sideways bleeding off over half the speed before gunning the engine to pursue the off-ramp bound Miata. Acrid smoke hung about the highway as the massive black Humvee plowed its way up the ramp in pursuit.
Traffic had already entangled itself badly due to the first speeding object, the second one had to swerve around or run down everyone at the intersection. A stalled semi with trailer blocked the way. They went right through it, the gunner barely ducking in time. The gun atop the Humvee hung at a strange angle as tin cans rained upon the vehicles on the other side it.
"Someone's not gonna get their soup cans this week!" the gunner shouted angrily.
"Campbell's can send a bill!" a backseatman replied.
"I lost them." reported the driver.
"Give me higher ground!" shouted the gunner.
"Sure, why not."
In front a huge glass panelled multi-level mall area. Large stairs visible through the glass.
Gunner: "Oh no, you are not gonna do what I think-"
Shattered glass went everywhere as the entire side paneling of the mall feels the multi-ton force of the HMMWV. A few people setting up for the day scatter, doing their best to avoid the raining glass shards. Potted plants crumble and benches flatten as they advance.
"Hope it holds us!" some shouts as they go up the stairs.
Up stairs they get a view of the area and quickly ascertain the location of their target. Due west but the floor is buckling behind them as drive not designed for this kind of weight. Driver puts the pedal to the floor and heads for another window.
West of the mall, people are unaware of the pursuit or even the accident just around the corner. A cop gives directions to some tourists. A guy reads his newspaper. Half the people in the area are on cell phones it seems. The window directly above the cop disintegrates as a Humvee passes through it. The cop looks up to see a huge black beast emerging from the 2nd floor of the mall. The guy lowers his paper to watch the vehicle head straight towards him across the street. He does not move.
The gunner peeks out of the roof of the vehicle to sunlight, bits of glass, and a decent view of shocked people looking up. The driver frowns as he tries to not land on anyone or anything important. The guy next to him braces for impact. The two in back give a mind boggling shout of enjoyment.
Impact.
Bounce.
Dodge.
Turn.
Accelerate.
The last chase begins... (I'll let you make this part up, unless there are demands otherwise)
