Looks like some special effect from the movie or the car anti-theft device, but the truth is not. This is the Tesla coil (powerful electrical fields) which attached on the car’s roof. This creation called “Tesladownunders Car Theft Protection ” made by Petter Terren at his home in Australia.  A Tesla coil is device to develop very high voltages pioneered by Nicola Tesla over 100 years ago. In its simplest form it is an air cored transformer driven by discharging a high voltage capacitor through a few of the primary turns. This sets up a high frequency resonance in the secondary coil. This resonance occurs between the inductance of the coil and the capacitance of a rounded metal object (typically a donut shaped toroid) and a very high voltage results in streamers directly into the air or sparks to nearby objects.
A Tesla coil such as this one with sparks of 8 feet equates to about 500,000 Volts. It is very hard to measure this voltage directly.
