People panic and get angry when sodas change the can design.
Roundabout aren’t only cheaper to build and maintain than intersections, they move traffic quicker and eliminate head-on and t-bone collisions.
Whenever you propose improving something this way, people do their Dana Carvey “Grumpy Old Man” for a few weeks, then get used to it.
Head-ons, yes, but I was damn near t-boned in one last weekend. The circle is fairly small (too small, really), so, when you are in it, the drivers entering from any of the four directions have the opportunity to t-bone you as you exit 90-degrees to the right of their entry. Had they made the circle a little bigger, and made them turn to the right more as they entered, then, yes, the t-bones would become more like side-swipes.
