I keep getting Yellow/Red signal alerts even when the signal ahead is Green, though it doesn’t happen on every signal, most ping as usual. The sunflower lights up momentarily too. I don’t know if this is being triggered when not touching the controls for prolonged periods - I am getting the rapid pinging when I need to let AWS know I’m still alive most of the time.
I'm not sure these are signal alerts, they seem to be AWS alerts for speed limit reductions ahead, albeit faulty ones. If you're driving from Paddington-Reading on the HST line, you get two of these faulty AWS alarms, and they both happen when you pass over a magnet relating to a speed limit reduction you need to make when when turning left at a junction ahead. The problem is that you're not turning off at the junction, you're going straight on.
