It takes maybe 10 minutes of driving to recharge a battery after cranking the car to start it. if yoy are running it less than that, you are just slowly draining the battery.

also, if it has carburetor, it will be on the choke until warmed up, that takes maybe 10 minutes too (longer in colder weather). If you never get if off the choke, you will foul the plugs and have a car tht will not start.

lastly, combustion makes byproducts, water is one, and by not running the car to get it hot (20+ minutes) once a week or so to burn that off, you will destroy the oil. Letting the car sit is better!
