Well, as I previously mentioned, because a direct connection is different than being connected through a differential and/or 
transmission.

I see. I wasn't referring to sheer torque forces being the problem, but rather the day in and day out repeated application and 
disapplication of power without the benefit of a any slack from a differential or buffer of a transmission.

I had some experience with this involving CV joints directly between a PTO and the load in a manufacturing application. There was a high 
failure rate with the initial use of sedan-sized units, and they had to move up to truck-sized units. This involved less HP and much less 
RPM than an automotive application.

So, four inboard motors with CV joints would work if they were up-sized, but then you would have more weight spinning at high RPMs, 
which would then require more precise balancing.
