Just what you want when driving home for the evening: some prat overtaking (which is fine), then pulling back into the inside lane only about 2 car-lengths ahead without any reason or necessity (which is not), then slowing down (which is just stupid):

When we inevitably pulled out to re-overtake, he decided to undertake (that is, speed up and pull in front of us, even though we’re in the overtaking lane). The distance between our front bumper and his rear one was, that time, probably less than 5 metres (at 110km/hour). He then proceeds to slow down again, and repeats the performance, left-lane overtake and all, only (it seemed to me) even closer than before.

The guy managed all of this one-handed, too:

Which presumably left one hand free to do what wankers best do.

Anyway: if you’re ever travelling up or down Sydney’s M5, I suggest you keep a keen eye out for maniac Suburu drivers. Especially if their number plate reads BK 66 TO. And avoid.
