They have a limited amount of cabs and people answering the phones. This is the busiest time of day for them. So it boils down to not enough resorses for a city the size of Springfield. At most they have 30 cabs and most days less than 20 drivers that show up and not enough phone lines or people to answer them. There's a old saying "don't put all your eggs in one basket". In the case of needing to get to work ON TIME I would look into other options..
Sorry i don't start until 7:45 pm to night I have class
