So, after two hours of wading through Gowanus and Staten Island Expressway traffic, some jackwagon has the balls to tell a driver on the X17 "your driving is terrible". Why don't you try it?!
There is always traffic somewhere. The question how much of an effort did the guy make? There are guys that sit in traffic and make no effort to get around it. Those I do have a problem with.
You can't assume that's what exactly happened. Besides, usually all lanes are clogged, and perhaps the driver wasn't close to an exit or any free-flowing lane.
