Many years ago when I was photographing a bunch of blues dancing in crazy low 
light, my friends with u4/3 had much better luck focusing using the f/0.95 lens 
and focus peaking on manual focus than I did with the Pentax.  EVF has its 
advantages and its disadvantages.   I suspect that it would not work well for 
John shooting motorsports, but for any subject that is reasonably static it 
should be good enough for framing, composition etc.  
In very low light it is often much better for things like composition because 
you can actually see what the camera will see.  When I’m doing astro, and 
astrolandscape, I find live view invaluable for focusing on a bright star or 
planet to set my focus to infinity.

The EVF on my Olympus E-m1 Mk II is very good. When I first looked through the 
camera I didn’t realise it was mirrorless. That model is quite long in the 
tooth now - I assume they have improved on it in more recent models.

One of the things I like which you can’t do with an optical vf is see the 
effect of changes to the exposure.

Last time I seriously looked which was a couple of years ago, I tried 
out a high end Olympus and a high end Fuji, I was seriously impressed.  
There was an occasional lag and the image looked a bit artificial, but 
seemed usable.  I thought a K mount camera with a good EVF would be fine 
for low light work, though I'd prefer a DSLR for any conditions where 
"I" could actually see.

I'm not saying you're wrong, but this seems more like a limited 
production, rather than a mass production item.  So it would of 
course be more expensive for what you get.
