Throughput would still remain unchanged. Suppose that the "lunch rush" is from 11AM to 1PM, and imagine that it's uniform for the sake of simplicity. Then drivers would end up being fully utilized from 11:10AM to 1:10PM, instead of 11 to 1. The 10 minute lag at the end where drivers are still finishing the queue makes up for the 10 minute delay at the start.
