I would wish that NBC would dial down the track noise a bit so the announcers don't have to yell over the noise. They are using track microphones to insert the sounds and it is too much, especially when Steve and Jeff starts raising their voices to get above the track noise.
Additionally, when they play in car communications, it would really help if they used a closed caption to help the viewers. Nothing bothers me more than 20 seconds of engine noise and static followed by one of the announcers saying something like "I agree with him" or "well that's really good info"
