Driving painfully slowly and kept veering onto the wrong side of the road. Apparently knowing how to drive isn't a prerequisite for being a taxi driver.
Driver in a grey Lexus who seems to have a short fuse if he has had someone merge in the normal zipper format. Drove flashing his light behind me, pulled out his phone whilst his engine was on at some traffic lights and kept flashing and turned off.
Clearly trying to intimidate other drivers in to a response - whoever this is needs to chill out and try a relaxing audiobook.
At least wait till there is a decent gap before moving lanes, pr1ck.
