Black SUV driving slowly on the left lane and then high beaming cars that past it as though it had the right of way. Was also cutting across lanes doing that. Happened at about 10.15pm on Saturday night. Driver was a female with a male passenger, both late 20s to early 30s. Male passenger was making obscene gestures as well while holding his phone camera. Drivers like there are a hazard, and need to really have their licenses revoked.
