'Am I tripping out?': Sydney driver's hilarious reaction to bizarre crash

A Sydney driver who filmed his hilarious reaction to a bizarre car crash in the city's southwest has seen his footage go viral.

The clip, which shows a sedan with two of its wheels leaning precariously on the roof of another car in the suburb of Liverpool, is incredible enough based solely on the nature of the crash.

But it's the response of the man filming, Sydney resident Vinny Lek, that's seen the clip garner so much attention.

"What the f**k! What the f**k did you do? What a f**kin' josh," he can be heard yelling at the start of the clip.

"How do you do that? How the f**k do you even do that? How do you park your car on top of another?

"Am I tripping out? If you want to park your car on f**king top of someone else's car, call this bloke right here. He'll park it. Wow, what the f**k."

After some time, a group of people can be seen trying to push the car off the one underneath.

The video has received more than 300,000 views and 4000 reactions in the 22 hours since it was published on Facebook.
