That fixed the bugger. About 12 hours ago I merged onto a lane of traffic with sufficient clearance to the next vehicle coming behind me.
The stupid shit kept getting closer to my rear, flashing their headlights & flapping their arms madly.
I didn’t just touch my brakes to indicate displeasure, I applied them violently, albeit briefly.
Sufficient for El Wanko behind me to also apply brakes. I suspect he also stalled the car because it took a bit of time to get going again.
