I don't feel too bad. I developed the flashing when you are clear habit ages ago in college and driving alot at night. I prefer a momentary flash simply because it is often hard to find the switch, compared to the light stalk in what I'm used to driving.
Now, when riding a motorcycle, I have a bit different approach, as I tend to wait until I have a complete clear shot past the truck and then get and go...but I hate getting trapped by a car and am stuck beside a truck in the wind and everything else.
But....that's a whole different ball game.
