I registered as a 'poll respondent' with IAM about a year ago to receive automatic notification of their upcoming surveys. I just got an e-mail from them that starts:
"Dear poll respondents,
Please participate in our latest poll - driving abroad
You may not have heard from us in a while. We’ve had a switch over of database systems at IAM Chiswick, and in the process we weren’t able to access poll respondents for a while."
Which is true, I hadn't received any requests for a while. I learned of the 'red light' poll through this forum. So was the most recent poll only completed by those who heard about it on the grapevine rather than the usual IAM respondents? and would this have affected the results?
