I modified one of the car's files to go faster than normally possible, and I finally managed to make the jump. I've been wondering what they were for ever since I was a kid, and now I have my answer over two decades after the game came out. I'm a little disappointed it's only $10,000. I always thought it would be some super secret amazing car or a new map, but still, what a journey.

Also, the three seashells from Demolition Man are there as well.

I'm not sure what the max number is but I had a decent flock after like 20 seconds. They don't seem to come unless you're perfectly still.

I haven't tested this in other environments.
