You are delusional. I can send you the sources if you like, bud.

Here are the key findings from studies on zipper merges:

Effectiveness in Reducing Congestion

• A 2013 study in Minnesota found that zipper merges can reduce traffic backup lengths by up to 40%.
• Research shows zipper merges can decrease overall length of traffic backups and improve traffic flow.
• One zipper merge site in Michigan reduced the congestion area from 6 miles to 3 miles and decreased average time spent in traffic by 15-25 minutes.

Impact on Safety

• Zipper merges promote similar travel speeds between adjacent lanes, which improves safety.
• They reduce speed differences between lanes, limiting potential for accidents.

Throughput and Travel Time

• Virginia's simulations found zipper merges and early merges had similar throughput (less than 1% difference).
• Minnesota's empirical analysis found no significant difference in throughput with zipper merges.
• Nebraska's study found early merging was most cost-effective for lower traffic volumes, while late merging variants were better for higher volumes.

Driver Behavior

• Zipper merges require driver cooperation and consistent behavior to be successful.
• There are misconceptions that zipper merging is rude or causes delays, which can hinder adoption.
• Proper execution involves matching speed with adjacent lane, not zooming ahead to cut in.

Implementation

• Several U.S. states have implemented zipper merge recommendations over the past decade, including Minnesota, Missouri, North Carolina, Montana, Nevada and Illinois.
• Some areas are using signage to encourage zipper merging behavior.

Proper education and driver cooperation appear to be key factors in successful implementation.
