Talk about it here.

Austin and HHH end up in a brawl and Austin looks for him in a parking lot, only for a car to run over Austin and take off. Don't worry Austin, Rikishi simply did it for The Rock.

They spent a lot of time just standing around Austin. Austin having to stand there waiting for HHH to spit was funny. Such a bummer of a payoff though.

Assuming that was a stunt man taking the bump, this is pretty slickly done with no camera cuts. Austin looks pretty beaten-up and gimpy just chasing HHH, so it clearly looks like he needs to be out for awhile.
