This question is for cyclists living in states which have enacted so-called "three-foot laws" (especially those who have been involved in getting such laws enacted). Do you feel that these efforts have been worthwhile? Has this law benefited cyclists in any way?
The state where I live requires passing at a "safe distance", but does not define what this means.
I have a feeling that there will always be a minority of drivers who will pass closely no matter what the law says.
