Do you believe that 43 cars in a starting lineup is too many?

The truck series has a standard starting grid of 36, but Busch and Cup races start 43 cars. Many of these drivers are overmatched for the competition they face each week. The results are crowded pit roads and inexperienced drivers causing havoc for those who are more qualified. Possibly imposing a minimum number of races be driven at each lower level would ease this problem.
