It would be great to be able to have the driving line, especially the braking line only option available as an “always on” option when driving around the map. The way I picture this working is the line always projects ahead of you on the current road you are on. If you make a turn onto a different road there would obviously be a delay while the line recalculates but that would be fine. This would be really useful for high speed free roam driving around the map solo or in a convoy.
