# Requirement change

I spoke to the operations lead this morning. Bike traffic has doubled and we are turning
motorbikes away while whole rows sit half empty. So from now on **two motorbikes may share one
standard spot**.

Things I want to be careful about:

- A motorbike that arrives should double up with a lone motorbike if there is one, before it
  takes an empty spot. Pack them, don't scatter them.
- A spot with one motorbike on it is **not free** — a car cannot have it. It is free again only
  once both bikes have left.
- Each bike still gets its own ticket, and both tickets name the spot they are sharing.
- Nothing changes about money. A motorbike pays its usual rate per started hour whether it is
  sharing or not.
- Cars and trucks are untouched: a whole spot each, two adjacent spots for a truck.
- A ten-spot lot can therefore hold twenty motorbikes, and asking how many motorbikes still fit
  should say twenty when the lot is empty.

Everything else about the lot behaves exactly as it did before.
