I'm running into an issue where after taking input from the user to turn on their car the inputs freeze up and the switch doesn't accept any other inputs. I know it has something to do with how I'm calling my functions inside the switch but I'm at a loss for how to correct it. Also, I'm fairly certain I've incorrectly implemented my clock inside startCar, it's supposed to subtract gas while the car is on.
