Thank goodness for childish behaviour. Got £330,000 Lexus LF-A underneath you, and a crowd of petrolheads begging for you to let it rip? You'd have to oblige.
Like the driver of this one, who couldn't resist a good stab at the throttle as he pulled away from a garage near the Nurburgring. Watch this vid and be patient - the black test-spec car goes first, but it's the white production car that gives it some death.
Pure race car noise, eh? That's what you get from a 550bhp V10. Kind of reminds us of a F1 car before they switched to V8s.
Now who wants one?
