Dr. Joe and John, too? Wow, there is a lot of horsepower in this thread!
How much acceleration is needed for swerve steering? Is Dr. Joe correct about 90 deg in 60 ms? What trajectory, maybe some kind of spline to reduce or eliminate jerks?
How important is swerve module moment of inertia about the steering axis? How important is scrub? Will overhung motor mass and fat treads be significant factors?
(Is Ether reading this?)
John, what do you think are the window motor attributes that kept this from being a problem in the past? Can a motor engineer help with this?

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
