well according to what I see and read and know about White Castles
White Castles usally has an Exit only drive
and looks like she cut across that drive
could be why the Cop didnt site the other guy
and it doesnt matter if the roads are empty or not, Bikes do not get
any extra rights, ride on the Right in U.S. and pass on the Left
Stop at all Stop signs and Stop Lights

maybe your drawin is off but if a car took that route and got hit
someone would have been sited

Hope your wife recovers ok and that this doesnt deter her from rideing
