Make the roundabout larger then, and you can keep just about the same speed. How can a roundabout take more mental and physical capabilities and slow you down less, than a stoplight on the interstate? That's very backwards, and not sure what roundabouts you've experienced, if that's the case.
There aren't stoplights on the interstate. That was the point I was making. (It got lost in the follow up.)
But to answer your question, roundabouts always require drivers approaching from all directions to slow down, lookout for cross traffic and assess other drivers' behavior. Stop lights have 2 modes that promise safe passage, and they can be set to prioritize routes.
