I suggest telling your son not to be competitive when driving. Don't drive angry cars. Don't drive when you are angry, let alone drink and drive. There are also some classical music that makes it easy to relax while driving. Or some Buddhist meditation songs will greatly improve our magnetic field. It's best to put a sticker of "Southern Guanyin Bodhisattva" on the car. Will bless him in trouble. Don't worry, this dream is not a sign, just a hint for you.
