Stepping up from low(ly) sedans, hiding high up in wheeled towers

Shiny the lacquer
that positively screams:
“Here drives no slacker
but someone lives their dreams!”

Lighting, screens gleaming
painted darkly, sized huge
with gadgets teeming
No measly subterfuge!

Keeps conniving
through windows tinted
pushing, driving
to self unstinted!

But not hard to figger
why the rush to bigger:

Mighty fortress wheeled
of menacing power
as cave, as crutch, shield
We’re King in our Tower!
