Video footage of mischievous motorists cutting across traffic and ripping a set of tire-smoking doughnuts has again hit YouTube, causing an uproar among concerned citizens and authorities.
The most recent videos, one shot in Oakland and the other in West Covina, show the latest in a string of incidents witnessed across the country as organized groups perform audacious choreographed tricks -- typically reserved for the most daring Hollywood stunt drivers -- on public streets.
California Highway Patrol officials are currently investigating the two recent events.
One stunt took place in West Covina, where hundreds of motorcycles blocked traffic on the 10 Freeway as a man proposed to his girlfriend. Video was shot overhead from an overpass.
In another, a video shows several cars spinning in circles while holding traffic near the Oakland Coliseum Complex. Officials believe six to eight cars were involved in the stunts, which took place on the northbound lanes of Interstate 88, with several others helping to block traffic.
