Excitebike 64 bug?

It happened by accident when I was playing properly at the beginning of the release. It was interesting, and it didn't seem to be on Niconico yet, so I gave it a try. Here's how I found it:

1. Choose the special course Excitebike 3D
2. Change the rider to Nigel (didn't happen with other riders)
3. Make all 3 other riders fall right after the start (It might be easier to do it like a video) That's

it. There may be other ways, but this is what I found.

I wonder how many people have found this to happen...
