Who is to determine what is excessive for anybody? Is there some sort of central planning committee, like the Chinese People's Congress?

Does a 1.0 liter Smart car get you to work? Definitely yes. Can you have fun taking corners in that thing. Heck yeah. Lots of fun, until you crash. Can you mod it to outrun a Ferrari? Sure, those Hayabusa engine mods make the Smart car a terror on wheels.

So, nobody is allowed to have a 8.0 liter V10 Dodge Viper? Or a 6.5 liter V12 Mercedes?

I see above that Grasshopper is learning fast !!! There is hope !! lol
