Driving across a lake on a motorcycle

I really doubt they have a lake that's just a multi-mile long puddle. They've got special bits that go on the bike that make them like jet skis.

Maybe. Or maybe they staged it like in Mythbusters.

Look up a guy by the name of Robbie Maddison. He surfed on one.

They have little bits attached to the bottom to make it work like a jet ski. It's not just a normal bike.
