Where I live close to Zürich at the sunny side of the lake, you probably have among the highest concentration of Porsches in the world. During the week a lot of woman drive their husbands 911 while he is making money. For them it's a practical car to drive into the city. So yes, a lot of woman in 911s and every now and then also a Turbo.
Of course I aggregated a bit, but most people don't see a difference between a 911 and a Turbo, so I don't think you draw too much attention.
Same in Chicago, I probably see more women behind the wheel of a 911 than men.
