I was squeezing by in front of a modern garbage truck this morning that basically had a glass side door. It was great: I could actually establish eye contact with the driver and sign that I was going to drive in front of him and he could give me small wave to go ahead. The driver of a less modern truck would have had no way at all to see me, much less communicate with me.
