Cyclists in pedestrianised shopping areas...... The way they bomb through so fast, not a care for anyone but their own need to get somewhere fast. This seems a relatively recent thing, over the last couple of years. Prior to that I'm sure they were more courteous.
Maybe its just a new generation of 'arrogant; rude; want it; want it now; sod everyone else; me, me, me' self-important individuals. Someone's gonna get pushed off soon...
