Has anyone else had any issues with TACC 'seemingly randomly' changing its set speed at specific locations?
It happened the other day on the M6 north bound around Birmingham and a little closer to home it happens in the exact same place on the A14 going across the top of Cambridge.
The speed limit symbol doesn't change but I watched the TACC speed cut dramatically on its own for no reason and you have to manually re-set the speed back to 70mph. Obviously when the TACC chops its speed in half, the car engages full regen to slow down which isn't great. This isn't phantom breaking, it isn't detecting an object or freaking out due to a HGV, I've watched the TACC set speed just change on its own with no input from myself.
A couple of google maps pins of where it happened on the A14 and happens in the exact same place every time:
This one it changes from 70 to 40
Girton · Girton, Cambridge CB3 0JN, UK
This one went from 70 to 30!
102 A14 · 102 A14, Milton, Cambridge, UK
It also happens going though this section westbound.
The speed's its dropping to don't really make any sense either and have no bearing on what is going on near the road or the time of day or any other traffic.
