What he said. The cagers here in Texas think they're in some kind of contest and get infuriated if someone tries to merge in front of them, or god forbid, pass them. I didn't even have turn signals on my old bike because if you try to signal and then merge on a bike, they speed up and cut you off. So I just used hand signals on a need-to-know basis. On my new bike I use my signals, because there's no way in hell they're going to out accelerate me. They're like "That guy's gonna merge in front of me! I better-Oh fuck, where'd he go? Hey! there's a loogie on my windshield!"
