It's a regional variation. Super common in some areas to see handbrakes used all the time (ex: Atlanta, very hilly, lots of names like "Druid hills" and "piedmont"). Super common in some areas to see handbrake usage discouraged entirely (ex: Northern states, where the concern is that it'll freeze up) Super common in some areas to see no one care at all because it's just flat everywhere (ex: texas)
