I'm a relatively new driver and just had a weird experience.
I was driving locally in a 30 limit when I noticed the car behind me had its headlights on but also a kind of bar of flashing white and blue lights all across the front of the car. I thought it could be an unmarked police car responding to an emergency so indicated left and pulled over to let it past.
It sped past, accelerating way beyond 30, at which point it appeared to be an incredibly dirty boy racer type car with huge plumes of dark fumes coming out of the exhaust and the entire back black with dirt. I felt silly because it was obviously not a police car and also completely thrown.
Has anyone else seen this?
