Went grocery shopping earlier and as I was driving off a taxi a few spaces away started to reverse. I beeped my hooter as he clearly hadn't looked and was going to hit me. He stopped, swung half into the bay next to him, clearly trying to avoid letting me go past and starts reversing again. I hooted again as he was going to hit me and he came storming out his taxi. I lowered my window and asked what his problem was and he started shouting. I shouted back and told him to fuck off and stop threatening me. He kept advancing shouting threats and blocking my way. I screamed telling him to move and by this stage feeling very panicked so I reversed around the bend and got out the car park asap. I got his taxi number. Normally I am extremely feisty and will stand up to anyone but I can't shake the jitters. I know he didn't follow me home but the paranoid part of me is worrying he will find out my address. Crazy I know. Should I call the taxi association and report him or let it go?
