Driving / Baking line in free roam

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.
