Add this video to the list of things one should never, ever do on a public road. Purportedly filmed in Sweden, the footage from the biker’s helmet shows the Yamaha R1 rider chasing what is said to be a Mercedes-Benz SL63 AMG (it looks like an SL AMG, but there’s no way of telling which one it is and whether it’s a regular or tuned model from the clip).

The foolish duo reach speeds of 299km/h (186mph) with the Mercedes-Benz going even faster at some points – and all this, not on the Autobahn, but on a single lane, two way freeway with cars constantly coming from the opposite direction!

Absurd? We think so. Watch the two and a half minute-long clip right below the jump and then tell us your thoughts in the comments.
