Of course an enclosed carseat or a harness is always safer, but I admit that too ride around with Silvia in my lap. My father has a BMW Z4 and when we tried to ride with Silvia in it, she would whine and try to dig into the seats to get away from the wind noise. I would suggest either riding with your pup in a friend's convertible first or on a test ride of the car you're wanting. That way, you know what the reaction will be before you make a decision.
