Here in MN they have been pushing the "zipper" merge... Their studies find that traffic moves faster if everyone waits to the last minute to merge...

Current ride. 2012 Pro RMK. Stock engine, Indy Dan's clutching with a team tied secondary. Dropped the gearing to 19/42. Went from a Turbo 800 Dragon RMK to this Pro, the Pro is 150% better sled than my old TD8.
