not necessarily. the only glitch i've faced is when im on the highway, i'll be driving really fast then out of no where, a motorcycle will just slide across the road sparking, as if someone just fell. but there is never anyone on the road its just the motorcycle. weird. WHERE IS THE EUROS?!?!
this isnt a glitch the reason no ones there is the same reason cars get lost. if you drive too far away the person will dissapppear but the bike wont because it is sliding forward too and since you are driving really fast in the time it takes you to stop you slide too far away from the person and they dissappear.
