What Speed 2 should have been about!

I was in high school when Speed 2 came out...and I hated it immensely. But it got me thinking about what could have been a better story and set up. For what it's worth, the scenario could still work for a potential Speed 3 or, at this point, an entire Speed reboot:

The Setup: A computer controlled amusement park (very Disney-like) is amping up its hi-tech abilities to allow for even more computer controlled capabilities and their newest, wildest roller coaster is having its grand opening. As such, there are various people of importance (politicians, etc) who get the honor of being the first ones to take the ride and it's a very big media event. Low and behold, our villain and his hired mercs finagle their way in and take control of the main computer, thus having complete control over the new coaster. You see, the main villain wants X amount of money for the lives of the poor folks on the coaster. Using a programmed chip, the villain sets the coaster on an unusual setting: the coaster will speed up and slow down at random intervals and at random areas along its track, thus making a basic rescue of the hostages almost impossible.

The Heroes: LA's elite SWAT team is called in to rescue the hostages. This could include Jack Traven or an entirely new character as they did with Alex Shaw in Speed 2. They have to try to climb up to and board the coaster, all without knowing when it will suddenly take off at different speeds. This, too, could lead to a few grisly deaths for some of the SWAT guys as well as the hostages.

The Climax: Our hero, after effectively rescuing the hostages and destroying the coaster tracks the final villain into a funhouse. What follows is a bit of cat and mouse until the villain is ultimately killed. Roll Credits.

This just a rough idea but I believe it would have made a helluva better sequel than Speed 2: Cruise Control.
