I kinda agree with you...after all, changing lanes is like a constitutional right. Often violated, always abused

. Violated in the sense that them road-*$ step on our right to change lanes, and abused in the sense that the same road-*$ use this right too much, like changing lanes every 5 seconds.
Sometimes, I don't even bother signaling when I change lanes; but most of the time, I do it more politically correctly by doing so abruptly like you do. Either way, like what my sig says, if in doubt, flat out. I can out-accelerate those selfish fools anyway.
