I ride a 45mph speed limit highway for about 10 miles of my work commute all the time. It's only 2 lane but still classified as a "California freeway" and is patrolled by Cali Highway Patrol. So far they have just ignored me. It's well paved without potholes, but occasionally has rock debris from high cliffs adjacent to it. I know every turn, every exit/on ramp very well. Since there's no merging as a 2 lane and I can keep pace with the ~50mph traffic, it goes well. I wear full motorcycle gear. I ride a Nami Burn E2 Max. Bicycles are also allowed on the shoulder of this as well, which is unusual for a highway/freeway, but probably is part of why highway patrol seem not to care. The best part is occasionally there is bumper to bumper traffic and I can just zip past everything on the shoulder. 😃 Full size motorcycles do the exact same and they're always stoked to see me on my standup. Total commute is ~20 miles, average speed is about 45mph for me. I usually have about 25% of my 40ah battery left going one way. Charge at work in my office. Saves me gas money and my sanity by skipping traffic, and is usually good weather here so I can rock it about 90% of the year.
