The point is not to needlessly increase the risk for other people using the road for the sake of showing off your car’s cool party trick.

But to directly answer your question: in fact, most people on a motorcycle will try to look at the driver, when possible, to check if the driver is looking at them to gauge whether the driver sees them or not. In the case of a Tesla, it’s impossible to know if the car’s sensors know you’re approaching...

Also, I don’t know any human beings that share a similar driving pattern as the Tesla while it’s being summoned. It seems to start and stop unpredictably and does so in a very jerky nature (and most humans do not drive as slow as in the videos, and yes sometimes driving slowly is more dangerous than driving regular speeds, and most humans also won’t drive on the wrong side of a lane, which the Tesla often does in videos I’ve watched... it’s just very unpredictable

A common technique for motorcycle riders, which also works for pedestrians, bicyclists and even car drivers, is to make eye contact with other drivers before pulling in front of them. The vast number of MC collisions happen because the other driver doesn’t see them. When the other operator isn’t even in the car, you lose a key safety tool.

The point is that a small "fender bender" between two big cars might be a fatality if a motorcycle is involved.

The "no driver" phrase relates to the likelihood.

Could be that you cant see motorcycle coming because your car blocks the view.
