dang... I'm glad you are OK! I've only ever had one person do that to me... he swerved into my lane, then back out, I could see him looking back and laughing in his rearview mirror... then he swerved into me again! I smacked his truck with my pump... but his truck was a POS so he just kept going... light ahead was red, so I geared down, got outta the saddle to chase and he cut thru a 7-11 parking lot and went right, skipping the stop light. Not sure WHAT I would've done if I caught him...
I always carry pepper spray, mostly for dogs, but ya just never know...
There is a fine line between "hobby" and "mental illness".
