TIE fighters fly around in space, space has no air, sound are vibrations of air, no air, no sound.
So if you can make your car completely quiet, then it sound like a TIE fighter.
But since that is impossible since you want to br driving around, you should duct tape some speakers to the roof and have a synth generate a continous TIE fighter tone, which would create the proper effect
And if you play it loud enough, you’ll get a free police escort!
My head cannon is that TIE fighters don’t make sound exactly as they zip around, but they do something to the electromagnetic fields or some other techno babble thing that causes other things, like droids, space ships, rocks, or skulls to scream with a Doppler effect like that as they zip by.
Look, in whatever far away galaxy the Star Wars movies are set in, sound travels through space. Pretty self evident since every spacecraft and space weapon in those movies is loud af.
No, physics still applies throughout all galaxies, it is still in the same universe.
However, one explanation could be that Star Wars takes places in a different universe, with different laws of physics.
