My wife hit my company car in the driveway and damaged it

You are correct. The car that was damaged by your wife, i.e. your company car, was not in her care, custody or control. Also, the liability did not arise out of her use of the company car. Your policy excludes liability coverage for loss or damage arising out of the use of vehicles that are "furnished or available for the regular use" of any family member. Hitting the company car with the family car clearly does not qualify as making use of the company vehicle.

The situation is really no different from those where your wife damages a stranger's vehicle with her car. Just because the vehicle in this instance was your company car makes no difference.
