That's probably why it's so "surprising" that there aren't more accidents.
The risks associated with turning movements can be reduced by adding deceleration/acceleration lanes.

Agreed. The majority of fatal collisions are non-intersection. Medians, carriage separation, shoulder barriers/warnings should be more of a focus than trying to turn rural highways into full grade-separated freeways or Super-2s. (400 is a different story, referring more to the TCH)
