Are you planning on leaving the gun in the car? Or just to have it handy while driving? For the latter a Remora holster between the seat and console works well, or attach a Kydex holster to the console where your leg will cover the gun. As for leaving it in the car no where is really safe but some areas are better than others. The seat back pocket, under the seat in a safe, in the trunk in a safe, under the dash in a mounted holster.
Don't question my right to own a gun and I won't question your stupidity not to.
You give Peace a chance, we will cover you if it doesn't work out.
