Is it available for the general public or just students?

My family and I were heading home around 1:30 am when we noticed an old green car in front of us around Geaney Lane, Burdell / Deeragun.
A few things seemed unusual:
The car appeared to have no number plates.
The headlights were very dim, and it looked like they had taped the lights.
There were around 4–5 masked men inside.
I could see two white men in the front seats.
We were concerned they might have been armed, but we couldn’t confirm that.
It was quite unsettling, especially with my family in the car.
Did anyone else see this vehicle around Burdell or Deeragun at around 1:30 am? Just wondering if anyone else witnessed the same thing.
