That's what I meant. If the posted speed limit on an "arterial" is 40 or over, the actual "ambient" speed is usually closer to 60-65. It isn't the speed per se, but the likelihood that drivers won't be paying attention precisely because they're on a road that feels and drives like a limited access highway, even though in fact it isn't. And if we're talking about commuter hours, then we're talking about people who are so distracted that they can't even be bothered to remember if they left their baby in the back seat, let alone look at the road when they're driving.

Mr. B., I don't know Sarasota at all, but I'm a little surprised that Indianapolis doesn't have similar roads - I know Columbus has many, and used to have more until they added bike lanes on some of the east-west connectors.
