This incredible video of a renegade tire smashing through the windshield of a car on the 401 is as incredible as it is terrifying. Shot near Salem Rd. in Ajax, Scarborough residentAndrew Sukhdeo是cruising along the highway when a flurry of activity occurs in front of him before the tire comes careening at his vehicle. The speed of the collision is so fast that the dash cam has difficulty capturing it.

It's hard to estimate the exact speed of the impact without knowing how fast the tire was moving (one assumes the car was doing 115+ kph), but suffice to say that it's remarkably fast. Miraculously the driver was not injured in the incident. Unsurprisingly, the video has gone viral on YouTube, racking up 175,000 views over the last two days. Have a watch.
