If it's known that cars are less manoeuvrable and have poorer sight lines, why do motorcyclists insist on gunning it past cars and swerving into the next lane before they've fully cleared the car they're trying to overtake. Not to mention the constant overtaking from the left, which is a completely moronic thing to do. If they're weaving in and out of traffic rather than just staying in their lane and spot, they're far less likely to sneak up on a car unawares and get hit.
