Went on the usually wed. night group ride last night, and it ROCKED!!!

An older women saw the group and came to hang with us, after a bit she and one of the fast guys took off, I hung along and they taught me a TON about pace line riding/drafting etc...we were over 21 the whole time except for one hill. Best ride ever!

Anyhoo...the point of this post, Tom (the guy) when he was in the lead would point at cars. It was like taking the eye contact thing to the next level, but I can see how some drivers might see this as confrontational. As an example, we were going up a slight incline, no bike lane, right turn lane into shopping center on the right, with a driver from the opposite direction about to turn left into said shopping center. The driver did not appear to be yielding to us, so Tom turned his head, rode with one hand and pointed directly at the driver. The driver jerked to a stop and we rode on.

Is this a common practice? Do you think it could be interpreated wrongly by already hostile drivers? It sure seemed effective, but as a lone female most of the time I don't want to risk ticking someone off.
