I don't have a solid answer to your question but instead I have a question for you:

What was it like???!???
I've been wanting to do this myself as the last 2 miles of the toll road is always empty at night and it seems the perfect spot to give this a go. A neighbor of mine says he used to do this fairly regularly in his SLK55 AMG. My biggest fear is a deer or coyote running onto the freeway.
Anyone else have experience with a Roadster at high speeds like this?
