Similar to what others have said, I rarely use high assist levels. I reprogrammed the controller because with 9 PAS levels, I only used up to PAS level 3. Now level 5 is a comfortable 18-20mph and I can go up or down a few levels to match the traffic and keep a comfortable cadence.

However, I sometimes do use full power when commuting on some roads with fast traffic. When cars are speeding past me at 50mph, I feel safer pushing the bike above 30mph to reduce the relative speed of the cars. Also 30+mph on a bicycle is... exciting.
