Super Stupid Question

I've noticed this as well. And it's so utterly annoying as I usually have all my characters on 1 hour missions, and therefore have 11-12 chars emerging from the quick-e-mart at the same time, which I conveniently placed at the end of a road to make it easy to "swoop" them all up again. This has become a lot harder when they just choose to stroll through fences, hedges, containers, buildings and pretty much everything else.
