Like others, inattentive 'cage' drivers cause us bikers some hairy moments at the rate of probably one a day giving us a near miss.
The other day I set out from home and within 500 yards I had had 3 cars attempt to wipe me out through their rushing (where to?) and inattention.
That put the 'willies' up me but thankfully it's not so regular as that ordinarily else I don't think I would have survived this long.
