Filtering on Motorway

[hightower]

Stationery vehicle for hazard lights. So how come Renault got away with making my hazards come on automatically when I slam the anchors on (really got to slam them on) in my Scenic? I don't buy that you should only use them stationary, and yes, I think it's a good idea to use when filtering past stationary traffic. Not so good for filtering past anything going faster than a crawl though (I class undertaking slow outside lane hogs on a motorway as filtering too, I wouldn't use hazards here).
