This is the opposite of dull.

where i live, the transit system is the same. after spending $5.60 a day (2 fare payments), you earn a day pass. after $100 you earn a month pass valid for the rest of the month

I once had the same with an electric scooter sharing service, I mean the big Vespa-style scooters. I rode around Budapest for a whole evening afterwards, went across the Chain Bridge in formation with a super nice German bike club on choppers.

Merriam Webster:

Buses is the preferred and standard plural for the vehicles, while busses is considered rare or incorrect.

Although busses was sometimes used before the 1960s, buses is now the widely accepted spelling in both American and British English.

Preferred: Buses (vehicles)

Alternative: Busses (rare, sometimes mistaken for the verb "buss," meaning to kiss)
