Should NASCAR Drivers be able to drive in lower classes?

In recent news, Tony Stewart is being accused of hitting and killing Kevin Ward Jr. Now I could go on for a while about this, but I want to talk about one of the big problems in this incident. That is that Stewart was driving a sprint car. If you didn't know, sprint cars are very far from professional series like sprint cup. So basically, it's like a professional baseball player playing little league. Doesn't seem normal, right? Stewart also isn't the only one to do it though. What do you think? Tweet me @Hunskey
