If I may, I will offer the comment that while I appreciate the survey and think it is pretty good, it does not offer a chance to speak to an important element of what Arlington County could do to help people feel safer on bikes – enforcement.
ACPD is not on bikes (except for rare exceptions like events), and rarely cites drivers for the type of infractions like close passing that make cyclists unsafe. Bike lanes without a plastic bollards are vehicle pullover lanes. You can barely ride for 1 minute without encountering a vehicle and I have never seen enforcement of that in Arlington. Then there are things like this.
