1) Have you ever been assaulted while riding? What happened and what did you do?
On our tandem, someone in a car hit my visually impaired with with a plastic container of wax or something. I pray to God regularly thanking him for not allowing me to catch them.
2) What measures have you taken to defend yourself and how far are you willing to go?
Dogs - Call the local animal control office. People? If contact is made, I file a police report.
3) This one is personally important to me.
I do not change my routine as doing so lets the idiots win. The last time that I had a vehicle incident (Verbal exchange - driver at fault) was on my morning commute. I started videoing my commutes. The next day the driver of the truck passed me with plenty of room and waved.
I also carry self defense grade pepper spray most of the time. When in the mountains or USFS roads, a bit more than that.
Oh yeah. ****.
