It's no foccin wonder with dickead bikers havin attitudes like that.
‘STINGER’ is effective against most four or more wheeled vehicles however it should not be used against vehicles with less than four wheels, especially motorcycles, unless under extreme circumstances. In these circumstances the Force Pursuit procedure should be consulted in relation to pursuit criteria.
Sad as that story is Lew surely it's down to the rider looking ahead and their speed bring appropriate for the traffic conditions. If all bikers did that then we wouldn't be in the situation of stingers or radio waves stopping bikes.
The only thing I can work out from that video (not on facebook so no idea what else is on there) is that the bloke doing all the shouting is a wanker.
