Well, today I rode down the middle of the lane, where I could see most of the cars were empty, except for the tinted window SUVs. When the backup lights went on in one car, I yelled "I'm behind you, don't back up! Thanks!" That seemed to work pretty well. To be clear, I do have a loud voice, so much so that my son said basic training didn't really phase him because I could yell louder than most drill sergeants, so he was used to it. Ha.
