The thing is, 1/3rd of games ends with the audience member picking the car. So, probability collapses to 50% in 2/3rds of cases.

It's a completely different problem than the Monty Hall problem, which can never end in the car being discarded.

The point I was making is that the problem (MH) is a lot more subtle than people give it credit for. Many of the arguments people make for how the MH problem is "obvious" seem to work for this modified game too unless you're careful with them.
