Just had a thought. Most helmet/dash video camera have a short, wide angle lens. That means that you have to be very close to the bike ahead to get a decent % of the frame filled. So, what looks like close to we sitting in our living rooms is actually a lot closer in the 3D.
I don't know what the ratio is over there but here the broken centre lines are generally about 3m long, separated by about 9m. The rate at which they go out of shot will allow you to calculate actual speed. Remember that when the coppers take your video camera after pulling you up for speeding.
