Matt Groening, creator of the Simpsons, is the latest celebrity convert to the Prius. He says “In a parking lot, when you’re backing up, you can drive silently and really scare the hell out of people!†“They jump because they don’t hear you coming.†It's Bart Simpson all grown up :D
Bart Simpson Drives A Prius
So does Tommy Chong!

Is there a list somewhere of all the Prius addicted celebrities? And now, with all these plug-in conversion kits out there... How many of them have made the necessary modifications? The Prius... a Trojan horse... re-introduced the electric motor into the automobile industry... now there's no turning back... once the batteries are good enough, they already are on the bench... the internal combustion engine gets left behind on the factory floor... that would make a sweet cartoon, the poor little piston engine... the big bad 12 cylinder poor little piston engine... all sad, gathering dust, rusting away in the dark corner of the old factory... while electric motors get brighter and brighter, batteries get lighter and lighter, and electrons dance all around... free at last.
hybrid cars or even plug-ins
hybrid cars or even plug-ins are just even made with a zero-emission features.. perhaps even radiators just like with kia spectra radiator, a cooling system are changed to battery dependent ones..
