those V12's don't like going slow since everything is stuffed so tightly in the engine compartment. Just need some airflow to cool down.
And don't worry, I'm not compensating for ANYthing. I just thought I would show a middle aged divorcee a good time. I know they can be kind of wild and try to live life again like a teenager so I gave it a shot and rented it but at 11 mpg in city traffic I was going broke so I kept the speed down and asked her to pay for her own dinner and split gas with me. She seemed upset and thought all I cared about was the car. Made me thinks she's just looking for a Sugar Daddy. Probably not a next time.
