I can imagine that that would make ya think what's going on.
Mistaken identity, looking for someone in particular ?
3 guys on two bikes, maybe shopping for a bike for guy number 3 ?
Your friend has a fan club and didn't know it ?
Think if that happened to me I'd seriously think about heading to a servo or place where there was plenty of people,,, and security cams.
then take it from there.
After hearing about all the recent bike jackings I'd probably give stopping at lights a miss too.
Trying to find a cop shop or a cop when ya need one would be near on impossible.
But, if there just happened to be one around i'd definitely attract his attention and pull over for a social chat.
Sad ain't it, once upon a time when ya saw a couple of blokes on bikes ya'd be inclined to pull over for a yak,,, things have changed.
the day i start looking over my shoulder for big nasty bikers will be the day that i taken out by some stupid fuck in a car ......
These dudes musta had the same problem,,, but they solved it
Or hows about an anti aircraft machine gun instead! They had some serious gear back in WW1.
