#12: Idaho
Average tip: 17.4%
Percentage of rude drivers: 4%
Idaho, famous for its natural beauty and friendly reputation, surprisingly makes the list of rudest states due to a significant portion of drivers—4%—displaying discourteous habits. With a tipping average of 17.4%, residents generally adhere to acceptable gratuity standards.

The influx of newcomers in recent years has led to tensions as long-time residents adjust to a changing cultural landscape. While the state is often lauded for its outdoorsy and neighborly vibe, subtle regional differences can create friction. Visitors to Boise and other growing cities sometimes note a reserved attitude that contrasts with the friendly expectations of rural areas.
