I don't find them too bad overall, but yeah, countless times i've been held up by the pointles overtaking trucks. And i've had to slam my brakes on a few times when they've done it in front of me.
I hate bad truckers and equally the bad bikers who think it's their God-given right to cruise down the middle of two lanes of traffic rather than a luxury afforded to them by other road users, and shake their heads at cars making maneouvres they're perfectly entitled to make. I recognize they're vulnerable road users and keep my eyes out for them, but i want to shoot those fuckers when i see them giving that disapproving headshake.
