Why he did it, we don't know. How he got his hands on the construction equipment is unclear at this point as well. What we do know: A Russian man who was apparently intoxicated commandeered a bulldozer and rammed it into parked cars before being yanked out of the driver's seat.
A video posted on the Internet -- filmed from someone several high stories above the scene -- shows a bulldozer colliding with nearly a dozen parked cars on the side of the road. Anti-theft alarms start sounding and he goes to the other side of the road to take on more parked vehicles.
After a few seconds, seeing that the bulldozer appears to be still for the time being, men start emerging from off camera, open the cab and proceed to beat the driver. The group violently tries to pull the driver from the cab. Eventually they stop and start beginning to explain to the gathering crowd what was going on. During this time, the driver -- who isn't getting much attention at this point -- pulls himself up into the driver's seat. He later stands without shoes outside the cab of his own power for several minutes and eventually gets down.
After five minutes, the police have still not arrived. The film ends with the man milling about awkwardly with those who could very well be the owners of the cars he just damaged.
All this occurs as other drivers weave their way around the incident.
Here's the YouTube version where you can hear all the car alarms:
