Well I personally find this spacing quite frustrateing.  So much so
that I use 2 motors on the engines that I have designed so far...

That's certainly the best way to do it, but also the most expensive.

possibly they found this spacing best for keeping contact on corners
and points?

I'm fairly sure there is a valid Technic_al reason for the spacing.
I can't check it at the moment, but contact points with points :-)
and especially the cross tracks would be my prime suspect.

I always thought the space between the wheels on a motor was 3 studs.
The problem with a dummy motor is that if the truck has 3 studs between
the wheels then the bogie plate nub is off center.

Harder to do, but the closer together, the less friction in corners.
