I have no idea, but this is how my Monday morning commute started, the instant I got on the highway. No sound of brakes, and the smoke didn't smell like rubber. Did the guy floor it? Is that exhaust smoke? Was that James Fucking Bond or something?
My afternoon commute was awesome! I did a "good deed" by letting a guy out of a convenience store parking lot when it was wall-to-wall cars waiting at the red light. I figured I was already fucked anyway because I was trapped in the "right turn only" lane to get on the freeway - not where I wanted to be, because I wanted to go straight but chose the wrong lane a couple of hundred yards prior. But once he shot out from the parking lot I realized he actually wanted to get across six lanes of traffic to turn left (a suicide mission) and felt bad because I gave him the "wave through" not knowing his ultimate plan. That said, because he was now camped out in the turn lane blocking traffic, I shot into the opening between his car and the traffic that was now starting to roll because the light turned green! YES! I was now in the lane I needed to be in, and he was on his difficult journey to make a left hand turn during rush hour, all because I played the role of "nice guy."
I'm going to guess head gasket failure or something like that. Looks like a lot of water vapor in the exhaust. So possibly a head gasket failure or something that would let a bunch of coolant into the engine.
I once had a turbocharger blow a seal and send most of the engine oil out the exhaust pipe. It looked something like that.
That could do it too, the exhaust didn't have that bluish color to it though. Unless the camera couldn't pick it up, but @Forbin would probably have smelled that.
It also looks like the smoke starts under his right rear tire. One theory from a friend is that he was trying to beat the car ahead of me on the ramp, realized he couldn't, and locked his brakes. But again, no smell of rubber in the smoke.
That seemed scary. Glad people knew to slow down, rather than speed through it probably causing more accidents.
Today some bonehead enacted "Dickhead Move #26 " on me. That is no matter how slowly and carefully you back out of your parking space (since you have giant Ford 15000 trucks on either side so you can't see for shit) some dick will come ripping through the parking lot and miss your back bumper by about two inches - and then give you a look like you're the bad guy!
