It says it right there, "rocket". While rocket doesn't mean it's a missile, going up to space with rockets is crazy enough for me, so riding one around is absurd.
Let's talk about where the mount [insert expletive] do you sit? Sitting in the middle will get your legs burnt off, and sitting on the back can only destabilize the rocket. That's leaves us with the front, which doesn't look very fun.
We are left with an uncontrollable rocket, which could explode at anytime, with stabilizing fins that don't look to be of much use, and with no where to sit, this is one crazy ride. It's not a question of IF, it's a question of when you will die from riding this rocket mount.
Next up is the craziest mode of transport in games. We move into the far future for this one.
