Re: Lost count...
People really don't grok the concept of scale when it comes to maps. Worse, throw in the concept of different traffic conditions at different times of the day, and they really get confused.
Case in point: The last 9-5 I interviewed for (in 1989), I was wearing my racing leathers. When the interviewer queried my choice of "uniform", I pointed out that he had asked me to drive up from Palo Alto to South San Francisco by 10AM ... and had called at 9AM. I knew I could make it on the bike, but there was no way I was driving the Bayshore without armor ... I got the job.
