Didn’t mythbusters do a thing on this too? but with gas savings?

Comparative studies of Superstreet intersections and regular intersections by North Carolina State University have shown that overall, cars move through Superstreet intersections about 20% faster. There are 43% fewer accidents, and 63% fewer accidents that resulted in injuries. I’m sure it’s going to be difficult, if not impossible, to convince drivers that making three extra turns just to go in a straight line is actually the most efficient way to go, but for roads that are already bulging with cars, it might be worth the effort.
