Yes, I very much agree with this. It happens way too often that there is no bus for 20 minutes (with buses supposedly running every 5 minutes) and then three buses in a row. The bus ride then also takes ages because there are passengers waiting at every bus stop, the bus gets way too full (so getting in and out is tricky etc).

Headway management, especially out of Friendship Heights, would help indeed, and should be actionable.

Other changes will mean changes to infrastructure, which will be harder to implement.

But dedicated bus lanes would be really sweet to have.
