You could make the same argument for hypercars like the McLaren W1, why do you need 1,258 bhp and sub 3s 0-60 times? Seems gimmicky and not practical for the road. But to that I'd argue, why not?
the difference here being that hypercars actually exist in the real world
One difference being that those in some way relate to performance of a vehicle and engineering ability to achieve it in a package which can be used for its intended purpose. This is just a vehicle with massive tanks strapped in and and obviously non production (not even remotely on path to production) package to make it achieve what has been proven since the 1970s as feasible for stunts.

By that logic any performance car is useless. There are, albeit few, people that do track these cars.
I don't think they're saying its bad, rather, the previous roadster has been in the works for 10 years and still hasn't been manufactured due to issues. Considering that how are they going to manufacture this by 2028? feels unlikely unless LLMs can help them here
