Braking before placed turns seems new. I've noted it doesn't work well on new 'unmapped' roads as it slows down for every turning trying to reroute.I don’t have EAP or FSD but spotted something last night with TACC I hadn’t seen before - it might be just a new situation for me and been around for years or is it a recent software update ?
I was ignoring the satnav directions as I wanted to go the long way (on motorway) to destination rather than A roads. I was on an A road and it was telling me to turn left as I was approaching each side road and whilst doing so was braking so I didn’t try and turn left at 40mph. It seemed more like NOA than I recall experiencing before.
As I was ignoring its route I kept having to accelerate each time to return to the TACC speed.
Otherwise I think it works well.
I assume it's the same logic that slows for roundabouts.
