Toyota's pain is Nissan's gain in the new ad "Dime," below, voiced by Robert Downey Jr., part of a brand-new campaign by TBWA\Chiat\Day in L.A. After Toyota's recent sudden-acceleration problems, the government has considered mandating "brake override technology" for all new vehicles. It's actually a somewhat common feature, found in models made by BMW, Volkswagen, Chrysler and others. But Nissan is the first to claim it as a sign of forward-thinking design, one that a viewer might assume helps you stop on a dime. Which isn't really accurate, unless you drive like you're playing hopscotch. "The only way this ad makes logical sense," notes Jalopnik's Justin Hyde, "is if the car stops while the driver is pushing the brake and gas pedals at the same time." Obviously, Nissan's not in the mood to let such pesky facts get in the way of a good, two-footed kick in the nuts for a downed opponent. Check out three other spots from the new "Innovation for all" campaign after the jump.
