Yeah. That’s how cloverleafs look. Is this the first time you’ve ever seen one? In case it is, they’re incredibly common and the most efficient and safe way to allow cars to go all directions without any stoplights at an intersection of two highways.
Yes, it is more common to have them be in a single direction, but the extra lane and bidirectional traffic doesn’t make it look any less like a leaf of clover.
They are actually pretty dangerous because they force traffic weaving. You have high speed traffic exiting the highway crossing low speed traffic entering the highway. In times of high volume traffic they get very hard to navigate and tend to cause a big choke point. That is why you will find many cloverleaf interchanges are being replaced.
Sounds like the danger you’re describing is a problem with all exits and on-ramps since all allow faster traffic to exit and slower traffic to enter the highway. I’m confused as to why it would be worse with cloverleaf as long as all of the exits are right exits. In my head, the dangerous merges are the left side on-ramps since you’re required to merge into the fastest traveling lane.

No, most cloverleaves use single lanes.

It looks significantly less like a clover leaf …

It is because they make cars weave
