Seams to but can't tell, there's no immediate change, just feels to be more clearance with BC 1.4. The lane centering is much better than before weather in BC zone or not.
My BC 1.4 works like you say except my display doesn't show the wider blue line in your picture.
2021 F150 Platinum.
I get narrow blue lines with a blue circle around the vehicle when everything is right weather in BC zone or not.
Not only does it change lanes for you, if you follow someone very long with your cruise set higher, it will notify you when it's clear to pass. I think you might need to be going like 20 mph slower for a certain amount of time. Nice
Lane centering is also much improved with 1.4.
Mine reads the speed limit sign on the left side that is ment be for the highway that just split off to the left and slows down fairly fast causing vehicles behind me close in fast. I turn right and the speed remains at 65. It also shows down for old speed areas that were changed years ago...
Any time it detects trailer lights, it disables BC. They don't want to take a chance it would cause trailer sway issues. Mainly for legal reasons if it were cause an accident.
Mine is working great, I think 1.4 but not sure.
Should I turn off OTA so it doesn't mess it up?
2021 701a Platinum.
Did all upgrades myself with help on here with Forscan and Dealership did all FDRS Module upgrades to fix another issue.
My bought used 2021 Platium did, $600 for 3 years.
I paid dealer $210 to upgrade all modules with FDRS and made several changes with forscan and now have Bluecruise 1.4 and it works wonderful.
