Again I have. taken my M3 DLD out to test on our Texas freeways (one lane each direction at 75mph). I tried both lane split and convergence at 65. The car held flawlessly. No twist of the wheel of dire warnings. A big storm hit just before I could try it at 70 so I will have to wait to check that. This is really a big deal. Lane split and convergence has really been a problem prior to this upgrade. When I first bought my car in April 2019 the wheel would jerk and the car would scream at me to take over at just 55 mph. I was concerned about whether they would ever make it really work. This, speed signs and stop signs or lights are some of the last things to go. I have had several cars in the last 57 years that I thought were really great (I really enjoyed them) but this one takes the cake.
