Simple Vehicle Control

I’ve looked through some vehicle tutorials before on this site and others that use some pretty advanced vehicle physics. My game doesn’t require that advanced of physics so I come here for help. The problem with my vehicle control is that it doesn’t steer correctly. It doesn’t move forward with the rotation applied. My vehicle will move like the ship from asteroids. Some help would be greatly appreciated. I am using C#.

P.S. I have attached my current script with some lines commented out. The lines commented out bring a result where the vehicle only acts correctly if you hold the correct keys down.

Is your vehicle meant to be like a car or other wheeled vehicle or a floating start-wars type? If it is the former, any reason you are not using wheel colliders?
