I love it when a safety feature meets an edge case.

I was driving along the highway, with adaptive cruise control on. There were cars in front of me and also behind me.
The car ahead of me set his turn indicator to the right and was decelerating for the exit ramp.
All good, heart rate 60bpm, there was plenty of space to get passed...
Suddenly, my car was like "PANIC, PANIC, EMERGENCY, BRAKE BRAKE BRAKE!!" And some automagic emergency brake triggered.
And I was like, "WHAAATT THEE FUUU...."

You cannot make these random emergency stops when a car is trailing your ass at high speed.

Yeah, it was something with the radar and the car fluctuating in front but anyway, nice feature.
