Of course it is. And, it will go far beyond realistic levels because of human psychology. Now, everyone who puts a foot on the wrong pedal will be creating bad publicity and blaming it on faulty accelerators. People will pile on because they have heard about the problems and assume their cars are faulty, too, even if they are not. It's actually too bad. Toyota employs a lot of people in the USA and has sponsored some nice CPS intiatives. When GM drove itself into the dumpster, the first thing to go was support for Safe Kids USA. You can pretty much be sure what will happen soon at Toyota.
I think it's better for the lives of all people on the road that Toyota ensure ALL their cars are working, regardless of human psychology. And perhaps as such an upstanding corporation, Toyota should have thought about that before covering these issues up and persuading government agencies to cover it up and doing every thing it can do lie and deny everything to the public. Admit the error, fix the problem, everyone moves on. Don't blame people for wanting to be safe. Toyota has messed up and messed up big time in this mess. They should be held accountable.
