With any luck, this is what I'm hoping for:
Blue/white pulsing engine lights
Cockpit control lights
Bright White headlights (I think there were what could have been headlights behind the grills - there are black holes in the one car!)
start up sound
engine driving sound
power down sound
when you start the car, the power up sound - dash lights would spring to life, engines ramp up intensity, flicker maybe
Steady on sounds - dash lights settle into a pattern
Power down - lights flicker out, engine whines down
Headlights triggered on or off from a button on the dash
Steering wheel connected to a potentiometer (?) to control volume
On off switch is the gearshift!
Ben Burtt: "The whoosh of Luke Skywalker's landspeeder was achieved by recording the roar the Los Angeles Harbor Freeway through a vacuum-cleaner pipe."
I even love that the body would essentially be a speaker cabinet.
