The worst car? Why? Because it's extremely small, cute and slow? Doesn't mean it can't be fun.
People rightfully get enthused whenever the McLaren F1 is mentioned, what most may not know is that both Gordon Murray ( designer of the F1 ) and Peter Stevens ( stylist of the F1 ) are huge Fiat 500 enthusiasts both owning several examples ( Murray at point even made a version himself with a bike-engine ) and Gordon Murray actually claims it's essentially a small sportscar in the way it handles.
Enzo Ferrari owned an original Mini Cooper which he used as a daily driver, not because he had to as he obviously could choose any Ferrari, but purely because it was fun to drive ( and practical no doubt ).
Small cars are also fun simply because there's more of the road/track left to drive on compared to a bigger car, and a car isn't automatically rubbish because it's unable to reach a certain speed.
Oh yes, almost forgot, after it went awfully quiet on the roll over front ( only saw it in one trailer ) and I feared they may have ditched it alltogether I'm very pleased to actually see some gameplay footage which confirmes it I hope.
So yes, OMG ROLL OVERS.
