It's interesting. I was just thinking I am unhappy is a car zips close to me but I am quite happy zipping along just as close between queued stationary cars. The difference must be the level of trust I have in the person in control.
And if you are doing the zipping, the person in control is the person who will get hurt, which will tend to focus their attention on getting it right. -- David Damerell <[email hidden]> Distortion Field! Today is Tuesday, September.
