Input: Text: so this was weird. happened about 20 minutes ago. 

was driving home from getting some maccas when i saw a cop car at a set of lights. i was going the opposite way to them. they hooked it around the corner and followed me around a corner so i pulled over to the side of the road, expecting them to follow me and pull up behind me. i have a pretty loud exhaust and a really loud sound system (which was turned up because fuck it why not) so i was expecting something to do with that. 

instead, they drive in front of me, pull over, and wait there for about five minutes. so i'm sitting behind this cop car not knowing if they're going to get out and talk to me or not. no lights either. 

they start pulling forward again so i decide to take off too. however, they pull on to the road and start driving really slowly in front of me. i'm driving really slowly behind them and i can't overtake them because they're cops. 

anyway, they pull back off the road again so i pull up next to them and wind my window down and ask if they wanted me to pull over. the driver just stares dead ahead. i drive in front of them and start heading home, with them right behind me. we're both doing about 10kph at this point. 

i get to my house and turn into my drive way. the cops just pull over out the front and watch me get out of my car then slowly drive away. 

i have no idea what the hell they were doing or why they didn't say anything when i asked them.
