If ASCII characters are used, the 256 bit key is calculated by applying the PBKDF2 key derivation function to the passphrase, using the SSID as the salt and 4096 iterations of HMAC-SHA1.

Slow by design.

I worry already thank you. Cars are starting to become wireless and, consequently, vulnerable

All of this requires physical access to the car

Why bother with the tire pressure when you can make instruments give false readings, kill a car engine remotely or turn off the brakes ?
