If I'm not mistaken, both of those cars had two drivers. The drivers might not have been in the same class. Look closely.
You're progressing really well, Regina. It takes time to learn the finer points of car control, and autocross has the added element of learning to "read" the course. But, like I was telling Matt, it's easier to teach a driver to go faster than it is to get one to slow down. You're not overdriving, you're creeping up on the limits of the car and that's good. Just keep pushing the envelope... and having fun.
