Uh, no. Assisted lane change was a feature of 1.2 and is standard on 2024 trucks. @Radar you have BC 1.2 from the factory.I think it's safe to say, if you don't have the auto lane change feature yet, you don't have BC 1.4.
Wait.. That link says basically all Lightnings just have BC 1.0, except for 2024 and newer have 1.2, and none of them have been updated since release? (As opposed to the MME's which have been getting updates)
