2011 rx
I noticed the article mentions upgraded "brake override" for the 350, but nothing for the 450h. Does anybody know if the 2010 450h (? 350) already has updated electronics where the braking action takes precedence if the brake and accelerator are inadvertently pressed at the same time. If not, I wonder if this will be a "retrofittable" safety upgrade.
The 450h is probably a different set up.

while you are driving press down on the gas and then while the gas is still press down press on the breaks if your tact falls off back to less than 100rpm you have this system in your car now. You do not have to press the gas all the way down just try it when you can drive around 60mph with no one behind you

Ziggy, I'm with you on the "Hope" part. I'm hoping they fix all the minor things pointed out in this forum, I've been holding off on buying the '10 for just that..

the hybrid has always had the brake override. This is to prevent the batteries from overheating. That is why only the 2011 lexus non hybrid models will have the brake overide put in

This does appear to be the case for my 450h. I did billy44bo's self test while rapidly accelerating, and the car definitely started braking. Glad to know that "drive-by-wire" override has already been implemented!
