I think the Commute Orlando piece makes more sense in their context, where crossing the on-ramp is just as hard as taking the lane. Particularly when they wanted to make a left afterwards. The OP is not in the same circumstance, and the on-ramp is to a high speed road, not a surface road.

Freeways cutting communities in two are a real issues in a lot of areas. Hopefully this is going to be less common in future designs now that planners understand the problem.
