Parking sensors activating during driving

Let me just start off by saying I’m new to parking sensors. My last car was an ‘08 reg and I’m now driving a ‘17.

I was driving to work at the start of afternoon rush hour. As expected I came across someone in front of me doing 35 mph on a 60mph is road for no reason. Anyway, I kept my distance because I couldn’t overtake and I’m expecting stupid driving.

About 50 metres down that road my parking sensors go off because a BMW is right up my backside. I jumped out my skin. The BMW backed off quite a bit and I don’t think they had been paying much attention before.

But my question really is, do other people get this sensor activation due to impatient drivers?
