Realisation about owning vehicles

My students were very excited to be able to buy cars, but were suddenly disappointed when they learnt they could only earn income from one car. I had to explain that while their houses earn them rent - regardless of how many they own - they can only drive one car at a time, so even if they own 10 cars, while they were driving one, the other 9 would be sitting in their garage.Some then had a thought.They wanted to know if they could pay their classmates to be drivers in their other cars?
