They don't race a car of tomorrow anymore. She tried them for 10 races. I can appreciate the clean slate thing but for the bulk of her career she has had the same car, other than the wholesale rule changes..
As far as an expert. I've invested a metric ****ton of time in my life watching this garbage, I'd consider myself pretty well educated on what you should expect from drivers and how drivers should run around a racetrack. And I have tons of respect for how difficult these cars are to drive. No expert, but you get the point. I'm sure a lot of other forum members feel the same way.
As far as the drivers, they earn a lot of money to do their jobs. These people are experts. If they drive like amateurs, I don't see what's wrong with calling them out on it. When DP showed up to NASCAR I was rooting for her. Every week she makes it more difficult. Now it's more like a running joke. I enjoy it though.
