Yes, the tricycle. Masterfully combining the exposed position of a bicycle with the space requirements of a car.
They really don't make sense in motorcycles, A large part of the point of a motorcycle is that you are willing to give up a lot of comfort and safety in exchange for having a very small nimble personal transport. Nothing wrong with this tradeoff, but why would want a vehicle that takes up the same amount of space as a car that gives you the safety and comfort value of a motorcycle?
At the speeds you can go on this, motorcycle is a bad comparison. Depending on the rear module used, this could definitely use most of the bike infrastructure in my city without a problem. There’s already a bike delivery company that uses e-trikes to great effect moving goods around the city center - in the downtown core 35kph keeps up with traffic 85% of the time, so taking the road is also an option.
I personally set aside the safety & comfort sacrifice of the motorcycle but cannot accept the performance loses. Similar to when I see people maneuvering a bicycle over rough or varied terrain while sitting down; you might as well be driving a car.
