Still, it’s a matter of driver expectation. After 10 km of freeway driving, most people won’t be prepared to see any vehicle pulling out in front of them.

I suspect that the business access in that street view used to be the TCH, bypassed when TCH was twinned. Something like that can be done at Whitbourne (or, as I digress, in Deer Lake too).
Edit: The only viable compromise that I can see is to build it like the right-in right-out expressway through Grand Falls - Windsor with a 90-kph speed limit.
